We are looking to bring in a HP 5DX System. This is the laminography equipment formerly known as Four Pi. I have our sales rep getting us a few references, but I wanted to get some opinions from the tech net. I am looking for input from someone wh

Hi I am using selective soldering to dip soldering the connector pins to the PCB and would like to know your experience: a) Is there a recommended dip or dwell time for the dip soldering? b) How do we improve the solder coverage in the TH? c) How t

a) Is there a recommended dip or dwell time for the dip soldering? Check your data sheet for the part. Dwell time is everything in selective soldering. Top side wetting is a good process indicator. b) How do we improve the solder coverage in the

Hi you need to dip long enough for the temperature of the part being soldered to reach about 20 degrees above liquidus of the solder. For the small parts we dip solder we had Sn62 and SAC387 baths set to 250 degrees and this seems to work best for us

Hello, We are planning to buy a desktop AOI system and were able to experiment with a Mirtec MV-2 system. Results were pretty good, except for some types of solder inspection. I am wondering if anyone has some experience with the Mirtec MV-3 (3D 5-

This is the perfect combination for the Mission Critical PCBs you require. All of our Airborne Customer Prefer a Leaded Solder to a Lead Free, and often require it. ENIG PCB construction is the strongest method of producing Mission Critical Systems.

My group supports a couple hundred lines all over the world. Most of them use squeegees but a few use either the MPM Rheometric pump heads or the DEK Proflow heads. I absolutely hate the enclosed heads. Flux separation, compaction, and the print q

We have been experiencing an issue with solder balls coming out of wave, both RoHS and 63/37, no clean process. It has been determined that a reduction in flux has all but eliminated the solder balls except for where we need to use board stiffeners a
