I guess you're adding the gas to keep the fingers clean - sounds likeyou got your threads mixed up on the Forum. Any way I would suggest not doing this. Gas is pretty flammable. I have pix of one our Hollis cleaning machines going up in flames cau

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

5 Zone HVA70 Oven Board 6 layer, 10" x 13" lots of space, most critical is 100 pin QFP AIM Water Soluble 487 Tin Lead paste on SN100C HASL boards This board is giving me disproportionate grief! I am running 23 in / min which gives me about 3.1 mi

we have problem in setting the density of a no clean flux for using before wave soldering . first we dilute the flux but we have many short circuit problem between the pads of edge connector,then we densify the flux all the short circuit is removed b

if two boards with different solder masks give different results on flux residue level after soldering with the exact same machine settings than it is clear that one of the solder masks is not compatible with your no-clean flux. could be the solder m

Tell the board shop to increase the cure temp of the resist as it is undecured especially if you have waxy/greasy resiues on the board and a brown tar like substence in the solder wave itself. If undercured then solder will not flow off the resist pr

Matt solder mask finishes gives the widest process window in view of potential amount of residues when using No-Clean. Shiny (glass like) finishes are more sensitive to residues due to lower surface area compared to matt finish. If the shiny finish i

Why yes, I regognize all the best. WML, I have an idea... I am going to call it, the Dunker. Instead of anyone foaming, I will get the wave operators to throw the boards into a rubbermaid tub full of flux/gasoline mixture and send through to the wav

I think WML ought to have some photos on how to do this...

what is WML ? can you please explain more
