masking material or a material line. l
After the masking material is dis- pensed, the system sets the valve back into place and picks up the UV wand, which is used to cure the material.
l
When the cure process is completed, the PrecisionCoat will select a second dispense valve, which is tied to different material line, and will outline various components, including dispensing between closely placed components.
l After the dispense valve is
put back in its place, the spray tool will be selected to com- plete the application of confor- mal coating to the PCB.

Coat AQC feature enables customers to isolate the components with a masking material (e.g., a gel coat, RTV, etc.) prior to spray coating the balance of the board. AQC can accomplish this easily in a few steps:

with the SCS Precision Coat and AQC, all of the above steps, including many possible varia- tions, can be programmed in a single coating profile, which can be executed without any user intervention. One of the biggest benefits of an SCS Precision Coat
is that the platform is designed for not only immediate needs, but is versatile to meet future demands as well. The flexibility of five heads/ valves and the AQC feature is enabling the PrecisionCoat system to be long-term solution for future applications. Contact: Speciality Coating

Whether you're an R&D engineer designing cables for a new product or a production worker checking hundreds of cables an hour, CableEye's unique graphic wiring display tells you what you need to know clearly and immediately.
Graphically see missing or shorted conductors, miswired cables, reversed diodes, and backward connectors. Print crystal-clear test results including the wiring schematic. Graphically compare two cables by alternating the display between your test result and the ideal cable. Run a high-speed resistance test loop while you flex the cable to check for

the selective machine to perform the rework. The board will then continue down the production line. The most efficient and
most popular system is one in which the selective soldering is in parallel with the AOI machine and linked by shuttle conveyors. The rejected board is shuttled off of the line to the selective system to be reworked. The board is then passed back to the line prior to the AOI. This allows the reworked board to be inspected again, ensuring that only quali- ty boards pass down the pro- duction line, with the use of only a single inspection system. With this procedure, there is every chance that the cycle time can be maintained and yield rates significantly increased. An alternative approach is to

By using AOI and selective solder machines that communicate with each other, scrap can be reduced and manual rework time can be saved. Contact: Pillarhouse USA, Inc.,
