If you have potting compound on your solderable surfaces, you can develop reflow recipes until they are picking cotton on Antarctica and they will not take solder. You should: * Tell your buyer [customer] not to purchase parts with unsolderable lead

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

If the package is robust enough to handle surface mount followed by a pass through the wave soldering process, we have had excellent results populating the fine pitch parts with the P&P machine, reflow, then mask the solder joints prior to wave solde

We have used JBC soldering stations many years without any major problems. Handpiece is lightweight and comfortable to use. Tips are bit expensive but worth of money. Go Nano for 0402 and smaller and HD for massive part soldering. JBC CD-2BB Solderi

Dear Pro, I want to confirm with you about conveyor speed. is 1m/s? We are using wave soldering but it is 1.2m/min, min not second. Pls, check it agian. The flux is not relative this error. It is relative no sodering, bridge. The solder bar is the
