I did convert YM 84V for 0402, base on my expperience , this approach is not really good.This model were not really meant for 0402 placement. Nozzle H ID is really small and prone to clogging, therefore cleaning every 2 hours is a necessity( not id

Couple of things. Type T thermocouples are solder friendly. However usually a header with screw terminals poses no problem as the temperature differential is nil. Getting thermocouple leads wet causes problems because two dissimilar metals + condu

Looking at the Emerald machines, they do seem like they'd fit the bill quite nicely. Other than the operating system, is one generation markedly better than the others? I have all the data on the X2 from the manufacturer's site, but what changed from

Amy, One way you can drastically lower the peak temperature of your QFP and prevent it from re-melting is to lower the solder pot temperature. If you're running 63/37 in your pot, the typical range for these is 460�F to around 500�F. You will need

Dave, We're reworking with flux and solder. We're observing "exploding" joints, as well...as though something is trapped in the joints (either excess flux not burning off during solder, or residual moisture). As mentioned above, I spoke with the f

One of our customers had us building "Pb-free" assemblies with a few Sn/Pb parts on them. THEY got rolling too slowly and we were not able to bring in the required Pb-free components due to lead-time (not Pb-time) issues. When they started requesti

MD, I totally agree with you A couple of years ago we had an ISO auditor in our company who was QC manager at Lockheed Martin. At lunch break we were discussing the erosion of American manufacturing and the effects outsourcing had on our economy. H
