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

we have two similar pcb from two different pcb manufacturer one of them passed the wave soldering without any short circuit and residue and another one passed it with many residue . don`t you think that the type of solder mask from these two pcb manu

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

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

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

What, Listen. Everyone know wave solders catch fire from time to time. I've only been a part of these fires a coupel times. Less than the number of fingers on my hands, so I don't think it's any different then anyone elses. Plus I havn't pulled o
