We'd guess that since your board fabricator could not remove this stuff with it's HAL-leaded process, you're unlikely to remove it with your soldering process that is likely to be pansy-ass compared to your fabricator HAL process. Hey, why not run a

Hello everybody, We are running a product through wave solder process using three different PCB suppliers. I have noticed that you can see more flux residues (water-based, No-clean flux) on one supplier than on the other two. All three PCBs run unde

Build in some flexibility to your costing. You will want to take into account how long various activities take and you will have to have your people do them in order to find out how long they take. In the end you will have to do your own costing bec

We had the exact same problem in early stages of lead-free. Very random positions of defect + some boards were 100% O.K. and others were an explosion of what I see in your picture. Turned out to be bad processing/materials from board house. I'm do

Me thinks generic profile + desktop and laptop computer boards= not happy time. Attach thermo-couple to appropriate location on said part/pcb. Make profile same as solder manufacturer / component manufacturer spec. There is no magic heater set poin

I have been working on Pb-free assemblies of screw terminals (terminal blocks). Unlike, other pin-in-paste conducive components, these component has square headed leads. We have been facing issues with the solder dripping into the oven. We were able
