There's a battle brewing around here regarding the use of press fit connectors in place of their thru hole counterparts because of suuposedly better reliability. Is there any validity to this statement? Up until now, we have only been going with pr

Really Rocky? What's the meaning of Russ' "if it will fit" in your scheme? As an alternative to your scheme, he could glue the nut on its side, tie a string through the hole in the nut, attach the other end of the string to the open door, and the

Hello Mark, Here in ECI, because the nature of our products, are using the method of press fit connectors in big numbers and although we have SMT components (around 200 per board) as well as T/H components we still preferred to use press fit because

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

Assuming your conformal coating material was selected with the intent of living a life in contact with oil, why doesn't your coating meet the IPC-A-610D requirement of that there be no voiding, no breaks in the surface, no loss of adhesion, etc? Furt

There are a few emerging technologies that have been growing in popularity for the past few years. Pin through paste, press fit connectors and selective soldering machines seem to be displacing custom fixtures. Most of the mixed technology boards o

Just curious if anyone else has trouble with the installation and inspection of DIMM Connectors (I know - these are through-hole parts!) We have boards with 240 pin DIMM connectors and occasionally a pin may not be properly aligned prior to press-f

There is a variation on the pins that come through on the other side. The pins that are deforming are roughly half the size of those which aren't deformed.There are no witness marks on the pins that are deformed, suggesting that the pins aren't fouli

| How would you mount a surface mount chip onto Perf board? I am doing a project for school and one of the chips is a surface mount, but everything else fits in Perf board. Any suggestions? Thanks Matt- Find some fairly stiff wire, the correct gau

Forgive the non-SMT question. That's why I hate through hole boards. Has anyone ever used Bareco wax on pressfit connectors, and how do you produce a consistent process for its application? Any drawbacks? Background: We have found a design issue with
