Check that your boards haven't been over plated. Too much plating in the hole can slump to the underside of the board during reflow. If you are then press fitting on the underside of the board you can have problems with hole diameter. If the hole is

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

We see this type of problem with a couple of our boards. It has proven to be a problem with the board. During manufacture at the board house the thru holes for the connectors are plated a little too heavy causing a smaller hole. If you haven't alread

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

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

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

We have used thousands of them with no problems. They will not aid in "connector retention" unless you have a shear force at exactly the right angle. This is an advertising joke. They will help with alignment of the connector. Open your holes up so t

Depending on the connector you should be able to use a standard cheap arbor press with some cheap home-made tooling. Standard arbor presses typically have a rotating disc with cut-outs, remove this and put a decent quality stainless steel block in it

Wendy, I've done this before using a machined piece of FR4 material to hold the board (machined like a DEK plate )in place at the press . It ensures that the boards are alway's in the right place and that none of the components are damaged..also sto

Wendy, we at ASG make electric presses for press fit connectors, and have made fixtures for AMP Zpak connectors. give me a call i believe we can help. 561-848-6746 Arthur | Wendy.. | | I found that little nugget a good one from my connector supp
