Automated Conformal Coating Spray Robot Issues

Posted by Sean Horn on Fri, Jun 01, 2012 @ 02:17 PM

There are many benefits to using a spray robot for conformal coating.  As always, there are some potential issues that need to be addressed prior to committing to a spray robot such as the MACCS 400.

 One potential issue with considering selective conformal coating with a robotic conformal coating system is misaligned components on the PCB which can potentially damage the spray heads which are moving along a set pattern on the board and the components themselves be damaged as they travel.  Spray heads are one of the most critical parts on the spray robot.  Repairing damage can get costly.

Why Use an Automated Conformal Coating Spray Robot

Posted by Sean Horn on Mon, May 21, 2012 @ 06:39 AM

A typical conformal coating selective robotic spray process consists of a programmable XYZ coordinate platform with a valve or valves attached to a controllable arm, depositing coating onto a printed circuit board in areas specified by the programmers of the system.  An example of this system is the  MACCS 400.

 Technology varies between the platforms and the valves but essentially they achieve the same result.  The goal is to deposit coating where you want it, removing the issue of masking which is required in batch processing with dip or spray booths.
