SANCO dispensing systems are compatible with a wide range of industrial fluids used in electronics manufacturing:

• Adhesives (epoxy, acrylic, cyanoacrylate)
• Silicone sealants and RTV compounds
• UV-curable adhesives and coatings
• Solder paste and flux
• Thermal interface materials (thermal grease, phase-change materials)
• Underfill and encapsulants
• Conformal coating fluids (acrylic, polyurethane, silicone, epoxy)
• Conductive adhesives and silver paste

Material viscosity range, pot life, and dispensing volume requirements determine valve selection. Our application engineers will recommend the right valve and parameter configuration for your specific fluid.

Piezo Valve — uses piezoelectric actuation for ultra-fast, non-contact jetting. Best for very small dot sizes (μL and below), high-speed applications, and materials with low to medium viscosity. Offers precise volume control without needle contact with the substrate.

Screw Valve (Single or Dual Liquid) — uses an auger screw mechanism to meter and dispense fluid. Best for higher viscosity materials, paste-like fluids, and applications requiring stable continuous bead dispensing. Single liquid for one-part materials; dual liquid for two-component mixing applications (AB glue, epoxy, polyurethane).

The right choice depends on your fluid's viscosity, required dot size, production speed, and whether mixing is needed. SANCO's application team will run material trials to confirm valve selection before delivery.

SANCO dispensing machines achieve motion positioning accuracy of ±5μm and dispensing volume repeatability of ±1% under validated process conditions. This is supported by:

• High-precision servo or linear motor drive systems
• Closed-loop vision correction using CCD/vision cameras
• Real-time glue weight monitoring (optional)
• Temperature-controlled valve systems for viscosity stability

Actual accuracy in production depends on material properties, environmental conditions, and calibration. SANCO validates these parameters using your actual material before delivery.

Yes. SANCO dispensing machines support multi-fluid and multi-station configurations including:

• Dual valve heads — two independent dispensing heads on the same gantry for different materials or parallel dispensing on large boards.
• AB two-component mixing — using the Dual Liquid Screw Valve for in-head mixing of two-part materials with controlled mixing ratio.
• DS Series dual-station — two PCB loading stations allow one board to be loaded/unloaded while the other is being processed, maximizing throughput.
• Multi-needle configurations — for simultaneous dispensing at multiple points on the same PCB.

Configuration depends on your PCB layout, material types, and cycle time requirements. Discuss your specific scenario with our application engineers.

SANCO machines use CCD industrial cameras with pattern recognition to automatically locate fiducial marks or component features on each PCB before dispensing. This corrects for:

• PCB placement offset (X, Y, rotation)
• Board warpage compensation (on compatible models)
• Component position drift in mass production

The vision system updates dispensing coordinates in real-time for each board, eliminating accumulated positioning error. This is especially critical for high-density PCBs with tight keep-out zones or small component pads.

The CANP 5G Pump is a precision material supply and pressure control unit used to feed dispensing valves and coating systems with consistent fluid pressure. It is particularly suited for:

• High-viscosity fluids that require positive pressure feed
• Continuous production where cartridge changes would interrupt the line
• Large-volume dispensing applications (potting, encapsulation, structural bonding)
• Systems requiring precise pressure stability to maintain consistent flow rate

It integrates directly with SANCO's dispensing and potting machines as the upstream fluid supply system.

SANCO machines use a proprietary graphical programming interface that allows path creation via:

• Visual teaching — directly click dispensing points on a live camera image of the PCB
• Coordinate import — import X/Y coordinates from Gerber, CSV, or CAD export files
• SPI/AOI integration — receive dispensing coordinates automatically from upstream inspection systems (optional)

Programs can be stored, recalled, and modified on the machine's touchscreen HMI. Support for MES integration and barcode-triggered recipe selection is available as an option.

Selective conformal coating means the coating material is applied only to the specified areas of the PCB — protecting circuits, traces, and components — while precisely avoiding connectors, test points, heat sinks, and other keep-out zones.

Compared to blanket spray coating, selective coating offers:

• No masking required — saving labour, time, and masking material cost
• Consistent coating thickness and edge definition
• Reduced overspray, rework, and scrap rates
• Programmable coating paths that can be quickly changed per product
• Traceability — every board's coating program can be logged

For modern electronics with dense keep-out areas and frequent product changeovers, selective coating is the production standard.

Three-Axial Coating Machine — moves in X, Y, and Z axes. Suitable for most flat PCBs with standard coating patterns. The valve angle is fixed, which works well for uniform spraying across flat surfaces.

Four-Axial Coating Machine — adds a rotational (R) axis to the valve head. This allows the spray valve to rotate and tilt, enabling:

• Coating at controlled angles around tall components
• Edge coating on PCB perimeters without overspray
• Tighter keep-out zone avoidance on complex board layouts
• More uniform coverage on boards with significant component height variation

The Four-Axial is recommended for automotive PCBs, complex aerospace boards, and high-component-density designs where three-axis motion cannot achieve the required coverage without masking.

SANCO offers six coating valve types for different film profiles and material requirements:

• G-300HP High-Pressure Valve — for high-viscosity coatings requiring consistent spray under elevated pressure
• G-500HP Diaphragm Valve — gentle, pulse-free flow for sensitive coatings and delicate substrates
• BF-028 Film Spray Valve — produces a flat fan pattern for fast, uniform film deposition over wide areas
• SF-073 Sector Spray Valve — sector-shaped spray pattern for area coverage with controlled edges
• G-420A Precision Striker Valve — narrow beam for precise edge coating and tight keep-out avoidance
• LF-001 Conical Spray Valve — circular spray pattern, ideal for conformal coating with even radial distribution

Selection depends on coating material viscosity, required film width, deposition speed, and edge definition requirements. SANCO provides valve recommendations based on your material data sheet and coating specification.

SANCO coating machines can achieve wet film thickness in the range of 20μm to 500μm depending on valve selection, coating material, spray parameters, and the number of passes.

Typical conformal coating specifications (IPC-A-610 / IPC-CC-830) require dry film thickness of 25–75μm for acrylic and polyurethane coatings. SANCO systems are tuned to meet these standards while also supporting thicker potting-style applications.

Thickness consistency across the board is controlled by:

• Stable valve flow rate calibration
• Controlled motion speed and spray height
• Temperature regulation of coating material (where required)
• Optional inline wet film thickness measurement

Yes. SANCO provides complete double-sided coating line solutions. The typical configuration includes:

• Side 1: Elevator In → Conveyor → Coating Machine → UV Conveyor → Curing Oven
• PCB Flipper — automatically flips the board to expose Side 2
• Side 2: Conveyor → Coating Machine → UV Conveyor → Curing Oven → Elevator Out

The PCB Flipper integrates seamlessly in the line and eliminates manual board handling between sides. SANCO has validated double-sided coating lines for automotive ECU, industrial control boards, and consumer electronics applications.

SANCO coating machines are compatible with all major conformal coating chemistries:

• Acrylic (AR) — most common, fast UV or solvent cure, easy rework
• Polyurethane (UR) — excellent moisture and chemical resistance
• Silicone (SR) — wide temperature range, flexible film
• Epoxy (ER) — hard, chemically resistant, difficult to rework
• UV-cure coatings — fast inline curing, reducing oven footprint
• Parylene — requires separate CVD process, not inline applicable

Valve selection and spray parameters are configured for each material type. SANCO recommends providing a material technical data sheet to confirm compatibility before process validation.

Keep-out zones are defined in the SANCO coating machine's software as exclusion polygons or rectangles that the motion controller automatically avoids during the coating path calculation. For a new PCB:

• Load a top-view image or import Gerber/CAD data of the board
• Draw keep-out areas directly on the board image in the GUI
• Define the coating area boundary and spray parameters per zone
• Save as a product program — takes 15–60 minutes for a new board depending on complexity

Once saved, programs are recalled instantly via product ID or barcode scan. Changeover between products takes under 2 minutes in normal production. Vision correction automatically adjusts for PCB placement variation on each cycle.

SANCO offers four curing methods, each suited to different materials and production requirements:

• UV Curing — mercury UV lamp, fast cure (seconds), ideal for UV-acrylic conformal coatings. Lower equipment cost, standard production workhorse.
• UV-LED Curing — LED-based UV, energy efficient, long lamp life, no warm-up time, narrow wavelength targeting. Preferred for heat-sensitive substrates.
• IR Curing Oven — infrared heat, suitable for solvent-based and moisture-cure coatings, and adhesive curing. Controlled temperature zones.
• Hot Air / Thermal Reflow Oven — convection heat, for thermal cure adhesives, potting compounds, and solder reflow processes. Precise multi-zone temperature profiles.

Material supplier datasheet will specify curing method and energy/temperature requirements. SANCO will confirm compatibility and set up the correct oven configuration before delivery.

Yes — inline integration is the standard configuration for SANCO production lines. The curing oven connects directly after the coating machine via a UV Conveyor or standard conveyor, creating a continuous process flow:

• Coating machine applies the conformal coating
• UV Conveyor transports the board under a UV lamp for rapid surface tack-off (prevents dripping)
• Curing oven provides full through-cure at controlled speed and temperature
• Vertical Buffer or Cooling Conveyor conditions the board before the next process or unloading

This eliminates manual board handling between coating and curing, maintains consistent curing time per board, and enables continuous production at rated takt time.

The SANCO Vertical Oven is a space-saving, high-capacity curing oven where PCBs travel vertically through a serpentine path inside the oven chamber. Key advantages include:

• Compact footprint — provides long effective curing tunnel length (equivalent to 4–8 meters) in a small floor area
• High throughput — multiple boards in the oven simultaneously for continuous production
• Precise temperature control — multiple independent heating zones with PID regulation
• Inline integration — compatible with SANCO's standard conveyor interface

It is particularly suitable for thermal cure adhesives and coatings requiring extended dwell time at elevated temperature — common in automotive, industrial, and new energy applications.

Yes. SANCO curing ovens provide fully adjustable parameters that can be saved as product recipes and recalled per board type:

• Conveyor speed — controls dwell time in the curing zone (seconds to minutes)
• UV intensity / lamp power — adjustable for UV ovens to match material energy requirements (mJ/cm²)
• Temperature zones — each zone independently controlled via PID for thermal ovens
• Air flow — fume extraction and airflow settings per material type

In a connected production line, recipe changes can be triggered automatically by barcode scan at board entry, enabling mixed-model production without manual parameter adjustment.

Curing of solvent-based conformal coatings and some adhesives produces volatile organic compounds (VOCs) that require controlled extraction. SANCO ovens include:

• Built-in exhaust ports for customer-supplied external extraction ducting
• Airflow management inside the oven to direct fumes to extraction points
• Optional activated carbon filtration for environments without external ducting

Customer facility must provide an exhaust extraction system meeting local EHS regulations. Duct connection size and extraction volume requirements are specified in the oven technical documentation. SANCO can advise on extraction system design if needed.

The Vertical Cooling Buffer Conveyor is placed after the curing oven to safely reduce board temperature before downstream handling, inspection, or packaging. It is needed when:

• Boards exiting the oven are too hot to handle or stack without damage
• Downstream equipment (AOI, labelling, packaging) has operating temperature limits
• Production speed exceeds downstream processing speed — the buffer stores boards and releases them at a controlled rate

It also acts as a line buffer, decoupling the curing process from downstream operations and preventing line stoppages from propagating upstream. Vertical design minimizes floor footprint.

A typical SANCO online PCBA conformal coating line with return conveyor includes:

• Elevator (In) — magazine-fed board loader, automatically feeds PCBs to the line
• Conveyor — transport between stations at controlled speed
• Coating Machine — Three or Four-Axial selective coating
• UV Conveyor — rapid surface cure immediately after coating to prevent drips
• Curing Oven — UV, IR, or thermal full cure
• PCB Flipper (for double-sided lines) — automatically flips board for Side 2 coating
• Return Conveyor — returns empty magazines or coated boards to the front of the line
• Elevator (Out) — stacks completed boards into magazines for downstream handling

This configuration enables fully automated continuous production — operator loads magazines, system runs unattended, operator collects completed boards. Takt times vary by board size and coating area; typical range is 30–120 seconds per board.

Yes, in most cases. SANCO equipment uses standard SMEMA (Surface Mount Equipment Manufacturers Association) electrical interface for board-available and board-pass signals, which is the industry standard for SMT and PCB automation equipment. This enables handshaking with equipment from most other manufacturers.

For mechanical integration, SANCO can customize conveyor rail width, height, and speed to match your existing line parameters. For MES or data integration, standard protocols (OPC-UA, MQTT, Modbus, or custom) can be implemented.

Provide details of your existing equipment interface specifications during the inquiry stage and SANCO will confirm compatibility and any required adaptations.

The SANCO PCB Flipper is an inline peripheral that automatically rotates PCBs 180° (front-to-back flip) without manual operator intervention. It is used in double-sided coating and dispensing lines to process both sides of a PCB in a single continuous pass.

Operation sequence:

• Board arrives from Side 1 curing oven via conveyor
• Flipper receives board, grips it on the edges
• Rotates 180° using servo-driven mechanism
• Board exits onto the downstream conveyor with Side 2 facing up
• Side 2 proceeds to the coating machine for processing

The flipper supports a range of board sizes and thicknesses. Edge grip design avoids contact with component surfaces. Flip cycle time is typically 3–6 seconds, not significantly impacting overall takt time.

The NG/OK Conveyor is a sorting conveyor placed after inspection (AOI or manual inspection) that automatically routes boards to one of two output lanes:

• OK lane — boards that passed inspection proceed to the next process or packaging
• NG lane — boards flagged as defective are diverted for rework or rejection, without stopping the production line

Sorting is triggered by a signal from the AOI system or operator input. This prevents defective boards from mixing with good boards downstream, maintains traceability, and allows the production line to continue running during NG board handling.

Yes. SANCO machines can be integrated with Manufacturing Execution Systems (MES) for production traceability and data collection. Available integration features include:

• Barcode / QR code scanning — automatically reads board ID at entry, triggers matching process recipe
• Process data logging — records coating program, parameters, timestamps, and results per board
• MES data upload — transmits production records to MES via Ethernet/TCP-IP, OPC-UA, or custom API
• Alarm and status monitoring — real-time machine status can be displayed on factory dashboards

MES integration requirements should be specified during the solution design phase. SANCO's software team can develop custom communication modules for specific MES platforms used in your facility.

Installation timeline depends on line complexity, facility preparation, and customer readiness. Typical timelines:

• Single machine (standalone) — 1–3 days for mechanical installation, connection, and commissioning
• 3–5 machine inline system — 3–7 days for full installation, alignment, and process validation
• Full automated line (7+ stations) — 7–14 days including integration testing, MES connection, and operator training

SANCO pre-assembles and tests the complete line in our factory before shipment. This significantly reduces on-site commissioning time. Operator training is included in the installation service — typically 1–2 days covering machine operation, programming, maintenance, and troubleshooting.

Yes. SANCO has in-house mechanical design, software, and process engineering capabilities to accommodate non-standard requirements including:

• Oversized or unusually shaped PCBs and substrates
• Special fixture and carrier designs for oddly shaped components
• Custom working area dimensions beyond standard machine specifications
• Non-standard conveyor rail configurations (e.g., bottom-support transport for large flexible boards)
• Multi-material or multi-process machines (dispensing + coating in one platform)
• Integration with customer-specific robotic or handling systems
