Hi Nicoleta, As a board shop, either are good choices but in my experience with my customers ENIG has alway been the favorite due to it is easier to work with in regards to not having to tweak your equipment. As long as the board shop that you are u

Im not sure that 0.004% is that critical in a solder alloy. If people are using our alloy and the Nickel increases we would most probably suggest running a dopant alloy without Nickel to bring the levels back down, it is very rare to require dumping

Dave is correct (as usual). Baking the boards might reduce blowholes but will definitely not eliminate the problem. Back in my hay days we had a huge problem with blowholes and we baked boards 24/7 with very little success in reducing blowholes (ev

I ended up finding that there were broken chords on the X-belt. I replaced it and all is good. Rob, Mydata is right. You can indeed end up spending lots of time and money trying to chase a transducer error. Things I would look at: 1. Lubing the X b

I'm not familiar with this particular MPM model, but in my experience, most MPM's are Computer Controlled. There should be a CPU embedded somewhere within the machine. Check to see if it's getting power. (I'm assuming you're already checked fuses/cir

I keep circling back to my initial choice, a Quad IVc (or IIc) because there are so damn many of them and despite their quirks/foibles/whatever, they are clearly capable of getting the job done. Specifically, I've got my eyes on a few refurbished mod

reash, Go directly to APS and get one of the APS GF-12 ovens. I have been using these for 15 years as a low-to-medium volume oven for general purpose reflow of CCAs up to about 12" by 12" with excellent results. I use them for BGA re-balling, underfi

We have a DEK 265 also. It may be the PNOZ (relays in a box) or the "in rush" capacitors "leaking" or "opening" causing your power supply symptoms. Went through something that sounds similar to your description of "power supply" problems. Your best o

Hi All, We evaluated and approved KESTER R520A for our default RoHS solder paste a couple years back. It's time to re-evaluate to see if this material is still the best choice. Please let me know your opinion on the solder paste you are using, and
