What is Your customers requirements? Is the PCBA mounted with front/back connectors? Will the PCBA be mounded in a rack and connected to opposite connectors on the other side? In this case, if the warpage is more than approx 1-1.5 % You will then n

We agree. We consider mounting holes and press fgit socket pads to be "critical contact areas." Consider taking steps to prevent the production of such solder splats on your gold to help elimate gold rework. We discussed this previously here on SMTn

| Does anyone have any reliability data /concern on pressfit rework/repair - is there any qualified /characterized equipment /tools present in the industry? | What kind of effect does it have on barrel plating quality (1.5mil avg.) after 1 time rewor

What we use for boards the engineers made to big is aluminum flat bar 1/8 to 1/16 thick about 1 inch wide. we fold it in 1/2 so it fits snuggly on the pcb and just press it on the ends before reflow. id assume the same thing would work on wave but

This is a common type of connector. We press them in daily. AMP has a lot of different type of tools and machines available for connectors. We just use a local machine shop to make jigs that fit a standard 2 ton press. It is quicker and les cos

Adam, The most common cause for this problem is a variation in the plating thickness of the through holes, particularly if they are Sn/Pb solder levelled PCB's. Most pressfit connectors require a fairly tight control on the diameter of the holes to

Hello, Is anyone using an SMT pick&place machine to insert single contacts into PC boards? I have some boards that have 32 female contacts for 1mm pins, and 16 contacts for 0.5mm pins. I have been using Mill-Max for these contacts, getting the sma

In relation to question 2 the vacume on them is quite sensitive so as long as you bring it down slowly the component is almost sucked up off the PCB so you don't have to actually press it down on the the component, and i have never experienced any so
