Hello Reflow Masters; I'm using an Omniflo-10E reflow oven. Due to high demands of our production in lead free process, can I use my existing leaded line as an native? Does this option affect the lead contamination of the solder in Pb-Free to go bey

Hello, I need an advice regarding the next issue: in the case of Assembleon Topaz or Emerald SMT machines, is there necessary to teach first the block repeat coordinates and after that the PCB fiducial coordinates when you do not have these coordina

Yes why did the Electroless Nickel layer split this is the ROOT cause. My guess is still that the resist was slightly miss registered over the copper and therefore poor adhesion of the Nickel ensued OR like I said originally the resist had contaminat

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

Hi Tony_D, thanks a lot for your answer! Yes I'd want to follow your advice, but Here in Italy I really don't find a Mirtec distributor yet. Also for me the defect coverage is a basic feature for the AOI and also in my company we have low volume high

I attended SMTA's copper dissolution webinar this morning and am almost convinced that this is not our problem. Still planning to do cross sections to verify but our dwell times are nowhere near levels that could cause a problem assuming good platin

this is really nice one ;) paper and cotton have lowest potential to generate static electricity see below, and usually is good practice to wear cotton glowe at least to one of your hands to not leave greasy finger spots on the gold finish of the PC
