As the technology has changed towards surface mount, so has the applying adhesive. In the past clinching parts would have knocked off SMD parts, but no that has all changed. So applying the adhesive via screen print is common and any thru-hole part

We have been running double sided surface mount pcb assembly for several years with no adhesive needed. We paste, place and reflow one side, then repeat the process for the other side. With Rs, Cs and small to medium ICs we have no problem with par

On TH parts we have been hand soldering. This last summer we purchased a Rhythm selective solder machine from RPS automation. I did a factory tour of both RPS and ACE since both facilities are about 1/2 mile from each other. In comparing the 2 c

Oops...just noticed you were referring to wave soldering. We'd still suggest a water-soluble flux, instead of the no-clean; especially at wave soldering. Also, checking pre-heat temps, and dwell time on the pot. Is the wave a chipper wave? If not

Greg, I totally agree with you that machine settings are very important in wave soldering and soldering in general. I disagree that lead free alloys can produce wetting like in the attached picture (leaded alloy). Lead free alloys have a much higher

We ran into this problem before, on all of our models. We never quite found out the reason, we do know that if the PCB is passed through a reflow oven that is extremely dirty with evaporated solder paste flux, it will make it extremely difficult (or

I have just carried out an evaluation project including Mirtec, MVP, Landrex and Viscom. If you are interested in my findings you can contact me offline. In short though, we found that each had plus points to them. If you could join together the outs

Hello everyone, I am new to the site, and I am hoping someone here can help me. We have a Manncorp MC386 and wanted to add a dual monitor video card to it. IT has an avalible PCI slot, so we bought a video card that will support dual monitors and
