We faced terrible void issue while using Sn96.5Ag3.5 solder paste, more than 20% void. We tried adjusting the reflow oven profiles but we did not have much success in reducing the void. Generally, we find quick preheat, high peak temp. and fast cooli

Production of 50000, is this per year, per month, per week, what? As for your budget of 80000 Euro, that is no much to go on. For a basic SMT line, you need at least 1 paste printer, 1 placement machine and 1 reflow oven. If you have any through-hole

Hi! Guys. I'm working in a SMT area and I want to have the best SMT line. What I want to know is: what would be the line configuration of a perfect SMT line?( automated solder printer-visual or automatic paste inspection-chip placement machine-IC pla

Dear anyone ; Every time that we run profile now ,we will create profile from recommendation of vendor flux and the some critical parameters such as thermal shock or others ... but I don't know that Do you ever create standard profile to be procedure

Hi Larry- Be wary of which IR systems you use, dark IR (ERSA) maintains only the positive effects of infrared use in that this infrared medium wavelength has the optimal absorbtion/reflection ratio between light and dark colors. Therby, guaranteeing

At present the band-aid fix is using epoxy 'dam' under the part and masking over the part to pervent excessive current leakage conmonent failure. These parts are first going through the reflow oven, where the epoxy dam is used to over come the leakag

| Hello everyone, | We found many cylindrical diodes missing during SMT process. Could someone tell us how to prevent this problem? Is it effective to change the shape of stencil apture or reduce fan speed in reflow oven? Thanks in advance. | | Gyve
