Hi, I am experience problems while testing wave soldering SMT components that are glued on the solderside (lead free). Between de leads of SOx type IC's and SOT's develop a great deal of solder beads. I have been using a RSS temp.profile while spr

Calling for an input from the Experts our there. Our customer is questioning the cleanliness of the no-clean product that we produced for them. We were asked to clean the board (localised cleaning) after rework (IC need to be changed due to an up re

The heat from a soldering iron will push raw flux across the surface of the board and into surprising places. It's bad practice to squirt liquid low residue flux on the board during rework, because the portion of the flux that does not get heated pr

Dear all, I am one of the founders of a small company doing electronics design + embedded software. Currently our prototypes are using increasingly complex smd components. When we started we mostly used atmel cpus, but now we are starting to use fpg

Hi Piet, We looked into this too at some length (we do a lot of FPGA and 16 & 32 bit micro designs) and every semi auto machine we checked out was to be fair, crap. Especially on the number & type of devices you could sucessfully handle, set up & a

Hi, I would go MYDATA rather than an "entry level" machine. The MYDATA low cost second hand units run the same software as their top of the line units, as well as taking the same feeders, so if you want to go faster and upgrade to a faster model, y

I my last company i had to battle all the time for tooling to set up jobs, i asked the product engineering manager to include extra panels in the costs for NPI to be used as reflow profiling panels, he told me they had never needed these before and t

QE's are the guys that sit in meetings asking the process guys --- "Uhhmmmm....my pie chart here says that we have 11 solder shorts on U1 for the week. WHAT'RE YOU GONNA DO ABOUT IT?" Unfortunately, most QE's dress nice, are tall, have gelled slic

Ah yes Mechanical Engineers. My previous company hired one Fresh out of College. Ink was still wet on his B.S. degree when he entered the shop. I passed by his desk. He had a CAD drawing on the monitor which he was feverously working on. It showe
