Hello, i would like to ask you if it is there some kind of literature where i can find more about Press Fit Technology? I would like to learn more about this technology. I found great literature Einpresstechnik from Mr. Tilman Heinisch. But i would

Since your question is general I will be general. The most important thing for press fit connectors is the design, and the proper tooling. Design considerations for the PCB are proper finished hole diameter, type of plating on PCB and connector or pi

The reason the resistors are fitted at a later stage is to complete the circuit but the values that will be fitted depends on the frequency range desired. My preference would be to leave them free of solder, limiting the options for the process used

In my previous job we fitted these connectors with bespoke gripper nozzles (ASM/Siplace) from bespoke trays made for these due to the high volume. It also reduces the risk of damaging the component further in case of a reject. However, at my current

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

WE are using press fit connnectors on a range of boards, one of which is posing me a few process questions . The Machine is a fully automatic machine. The problem is intermittent and I can't seem to put a finger on it. An array of connectors ( consi

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 Mark, I'll assume that you are currently wave soldering and would like to eliminate that operation by using pre-forms or press-fit connectors. Solder preforms or solder flux bearing connector leads usually do not require any hole size changes,

We are a CEM and do exactly what you describe i.e. teach the image of a non-populated part and apply to all no-fits for that package style. Works very well with our equipment (Yestech)provided the visual signature of all your parts are sufficiently d

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
