flux residue after HAL

Electronics Forum | Wed Dec 27 20:33:50 EST 2006 | greg york

water alone especially cold is not good enough, how do you check for hasl fluids when most residues left behind after improper cleaning are non ionic. Use 40C saponifier followed by heated rinse then cold rinse then DI rinse followed by dry.Nylon bru

no-clean flux vs. impedance

In theory, no clean flux residues are electrically benign...period. Here's a good test. Subject the board to some moisture/humidity, and have your circuit designer ohm-out any areas that may be affected by conductive material. Option B: Have a la

spray gun for flux

Electronics Forum | Tue Dec 18 04:13:27 EST 2018 | bukas

hello everyone, i'm looking for a spray gun that can withstand flux aggression. I made air controlled prototype for ersa wave machine, but air guns wear out quickly and start to leak. I was thinking about Binks model 95AR or something with stainless

I require some feed back from any one who knows about using a voc free flux in a nitrogen wave solder machine soldering both through hle and smt componants. What disadvantages are there when using this flux? Do you have any contact details with

Amtech 4300 no-clean+washable flux

Electronics Forum | Sat Oct 29 20:29:30 EDT 2016 | adamjs

Posting here because all the threads asking for feedback on it are locked. We have been extremely happy with the 4300 tacky flux for BGA attachment. Not only is it both washable and no-clean (i.e. wash-optional), it was also the only tacky flux tha

Wave flux and profiling

Electronics Forum | Wed Dec 20 04:43:36 EST 2006 | greg york

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

BGA flux dipping process

Electronics Forum | Mon Jun 15 15:33:51 EDT 2009 | hegemon

IMHO I would suggest that if you are using flux only during a BGA placement on a small run, that you first tin the pads with your soldering iron, then level the pads back out with wick. Accomplishes two things; adds a little metal to the joint to ma
