Is anyone has experience on problems with press-fit on Ni/Au board finish. Connectors pins are SnPb finished. I am particulary interested by experiences or documentation in very agressive environmental conditions (avionics or space buisness) Thanks r

I have only seem problems so I would suggest you don't do it.

General comments are: * First place I would look is the supplier of the pins that you are trying to install. Most suppliers that sell press fit components have done a good deal of work to qualify the component and will have all the specifications yo

Hi, we do Sn plated I/O pinning insertion into Ni/Au thru' holes. no problems here so far, as we cater for the "interference" (fit-allowances) of the I/O pin into the thru' diameter, via improved PCB thru' hole designs. before this cater/considerati

Mario, If you are looking for a cheap press to do press fit connectors, then you are asking for trouble. Now, and in the long run. ASG out of West Palm Beach makes a very good press. We bought a 5 ton version and are able to press up to about 2500

Sal: Hey that customer standing around staring at you sound like fun, yeh right!!! Wolfgang makes good sense, but, in addition, I�d like to drill-down on board fabrication (har har har) a little bit (har har har) more. You say the holes are the cor

Accuracy of the arbor press might be made better by tightening the adjustable gibs on the ram if any. If you can use support under the board have the ID of the support just slightly larger than the pins being pressed. Janesville Tool makes an accura

Cut the sucka off the board and move on.

Oh yeah, I've seen this before! Generally, if the hole sizes are correct (including plating), and the PEMs are within spec, we've found that this is most commonly caused by insufficient support of the PCB during insertion. If you can eliminate supp

We are using HASL board for Press Fit, without problem in the past until recently. Now we are seeing the solder in the PTH melt and block partially the PTH hole during the reflow. It gives problem when Press Fit. Anyone has advice on this?
