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

Hello We have recently started to work with press fit but we are finding problems to reach the specifications in terms of hole deformation and whiskers. Do someone have experience in key process parameters and PCB design specifications (PCB harness,

Hello Jim, Is any special tooling required for press-fitting a connector?

Hello Floyd, Yes, special tooling is required. The tooling usually consists of a press, push-in tooling and support plate tooling. The presses can range from relatively simple arbor type presses to automated hydraulic presses with sophisticated con

We use a few different style of press fit connectors, terminals, studs, etc. We use a tabletop arbor press for most everything we do, but a lot of times we will see some measling or slight delamination around the holes for the press fit part. Is ther

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

You could check the data sheets/web sites from the manufacturers of the press-fit parts. They typically will identify the recommended tooling/equipment necessary to install their components. Generally, pneumatic presses are suggested, with controll

Are you using specific tooling for each part, or just generic? If so it could be pushing down at an angle and slightly tearing the PCB. We use the same style press as you but make custom fixtures to fit each connector and hold each PCB tight.

Currently we have started seeing an issue around a scuzzy connector.The problem being that during insertion of this connnector a couple of pins refused to be inserted and as a result fold over, this folding of the pin is causing the pin itself to fra

Sal: If it�s not the PCB, what about the connector itself ? Is it from a different production lot with some unregularities ( dimensions, tolerances, pin alignment, material weakness)? How about handling, storage, shipping causes ? Could it be a tooli
