Basically it pretty standard to run through the board. For programmers /manufacturing engineers it’s a catch 22. If you check everything management is complaining it takes too long. If you don’t check management is complaining because of rework and y

Rich Here's what Humiseal says: Thermal Properties The coating must be able to withstand localized thermal 'hot spots' generated by components. High temperatures can cause short-term changes in coating characteristics, such as softening and lowered e

Rich That is a standard reaction with Humiseal 1A33, nothing to worry about. Find a board that was coated over year ago and had been heated up at all and it will be an amber color. It does not violate the IPC for discoloration. We have coated boards

Are there SMT mechanical components like that could be used for orientating PCB-level optics on the board and do not require holes in the board? Their final position would solely depend on the reflow. A height of 1/8" would be sufficient. I was con

There are several shapes that are standard - circle, triangle, two rectangles, cross... I personally have the impression that most people use circle. Anyway, all systems on the market should be able to recognize the standard shapes. Most imprtant is

I have identified a Board design issue and having trouble convincing others of my findings. I have a BGA (Sn63 balls, +1500 IO, 0.6mm ball, 1mm pitch, with heat spreader plate)that has a high incidence of solder shorting on the corners. The board i
