At times the orange peel effect can be from excess flux improperly removed. Our company strictly provides the service of selctive conformal coating application. We quite often see this. Most times if the board is simply "water washed", or IPA washed,

There are factors that manufacturers have taken into consideration when dealing with coating. On/off times, dispense speeds, heights, etc.. Dedicated software with tools to easily map out paths are a godsend. We made our own coating machine with a s

Bubbles after coating

Hi all, I need some pro help me with issue bubbles after coating. some information for some pro: Machine: Asymtek Chemical: Achime AVR80 Oven: IA 4 zoon4 ( setting 100 100 90 80 conveyor speed: 0.6 m/min). I had happened before and after the oven. W

I have boards coated with Humiseal 1B73. At a late point mfg. site we need to remove a series of 0603 resistors for optioning purposes. I have been trying to determine the fastest, easiest way to re-coat the pads after removal. Drying time of the

Preheating a board with metalic coating on both sides

Electronics Forum | Tue Jul 30 17:45:56 EDT 2002 | davef

What's this 'metalic coating on both sides'? Is that like a 'two-sided board'? I expect that your 200�F is the primary side temperature just prior to entering the wave. If not, you need more juice [depending on your flux and all that]. [Some mode

Preheating a board with metalic coating on both sides

Dave, thanks for the reply. These boards have metal plating covering 99 percent of both primary and secondary surfaces. The only places without the metal plating are the extreme outer edges and about an 1/8 inch surrounding the plated holes. We do

Bubbles in Conformal Coating

Hi Steve, Make sure your spray head is all the way down. If so, try slowing your rate of speed over the part. Which head are you using to coat this part?

1B73LOC Conformal Coating

Electronics Forum | Mon Jun 25 10:59:49 EDT 2007 | simsj

We're using the 1B73LOC conformal coating from Humiseal. We've seen some bubbling of the coating. Their tech handbook suggested reducing our oven ramp speed. Does anyone have a good profile for this? They've always pointed me to Nordson, and Nord
