I think it is very nice to have the feature of getting informed when someone answers to a question I put on the smt.net. But (and that's a big but): If you send out an email why can't you just include all the informations you want to send in the emai

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

Most of the semi-con is using SAC305 balls. Only the PCB assembly house feels the heat, but semi-con never feels any pressure.

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

We have a similar board and came up with a quick and dirty solution. The board locates via pins onto a manual desk press with strategically placed feet to break the mouse bite. Not really much quicker than doing it all by hand, but after a thousand p

I always made tests with gauges on top or bottom surface of the PCB, before, during and after the process that we wanted to check. But I never tried to do it on internal layers of PCB. Don't know if that is possible. Regards

Hi, I have pcbs (Duroid/RT 5880) with raw copper, soldered in vapour-phase chamber at 230 degrees Celsius. During soldering, copper gets tarnished. Cleaning with Vigon A250 removes the tarnished layer. Indeed, in the VigonA250 techn. datasheet it is

Tmo, Thanks for your reply. It gives good advise about how to perform tests. The type of strain gauges that I want to design are inside the PCB at various layers and I want to read the data during the press step. Do you know if these prefabricated

Hello all! For my mechanical engineering study I want to etch a strain gauge in the Wheatstone bridge configuration in a copper layer of an PCB. The goal is to measure the strain occurring in an PCB even during the press process! We can measure with
