Dispensing systems for electronics manufacturing

Automated dispensing systems apply material repeatedly at programmed positions. In electronics production, material properties, required geometry, deposit volume, valve, needle and process control determine the result together.

How automated dispensing works.

A motion program guides the dispensing head along defined points and paths. The SD-400i supports points, lines, circles and rectangles. A CCD camera assists teaching and positioning.

After a needle change, needle alignment and Z height can be calibrated automatically. This supports setup, but actual dispensing quality still needs to be confirmed using the real material and a sample assembly.

Typical dispensing tasks.

Dots and defined volumes

Material is applied at specified positions when location and volume are critical to the function.

Lines and contours

Programmable paths support continuous deposits along defined geometries.

Different materials

Depending on valve and material data, different tasks can be evaluated. Actual compatibility is defined for each project.

From material to a stable deposit.

1. Characterise material

Viscosity, fillers, pot life, temperature behaviour and curing affect the valve and process settings.

2. Program geometry

Position, paths, clearances, needle height and deposit volume are configured on the actual assembly.

3. Calibrate and inspect

Needle and Z height are set. Samples show whether shape, volume and repeatability meet the requirement.

Selection criteria for a dispensing system.

Material and valve principle

Flow behaviour, particles, fillers and required volume determine which precision valve suits the task.

Dispensing area and component height

PCB, panel, fixture and tallest components must fit within the available working space.

Deposit geometry

Dots, lines, circles and contours place different demands on speed, distance and material flow.

Process environment and limits.

Material supply

Container, compressed air, degassing and refill concept influence process stability and operation.

Downstream steps

Curing, transport and inspection need to fit the dispensing process in time and space.

Sample trial

Positioning accuracy and working speed alone do not guarantee a suitable deposit. Validate the result using original material.

Information needed for system planning.

Useful inputs include the material and safety data sheets, target volume and geometry, PCB size, component heights, fixture, cycle-time requirement, curing and quality-inspection information.

Why a dispensing trial is necessary.

Viscosity, temperature, needle, valve, distance and speed affect the result. A test with original material and the actual assembly shows whether the required shape and volume can be achieved consistently.

Frequently asked questions about automated dispensing.

Which geometries can the SD-400i program?

The manufacturer information lists points, lines, circles and rectangles as well as position correction.

Which dispensing valve is required?

This depends on material, viscosity, fillers, required volume and geometry. The system is compatible with different precision dispensing valves.

What is calibrated after a needle change?

The SD-400i supports automatic needle alignment and Z-height calibration.
