Dave, There is not really a �smart� or scientific way to check this but I know of easy ways and very effective ways. Fex. an easy way to check is with a 3� spatula, you hold the spatula at the same angle as the board and drag trough the wave simula

Good day, can i seek an advice regarding wave soldering. Will it be advisable to reload the board two times to improve its barrel fill volume? If yes, what is the maximum number of times we can repeat wave soldering on the same board. If no, what

The standard machine is set from the factory at 7-9 degrees, 7 is the most standard, why are you considering the change? before doing any thing to the machine, first identify why? what type of defects are you seeing? I have found, depending on the t

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

Back in the day, we had a small solder pot used for dipping ICs that were freshly removed from defective boards. What tool did we use to clean the dross? A small piece of card board. After the card board got too toasted, we'd grab a new piece of c

Hi Shrek - Not sure why you think adjusting dwell time and preheats is a sales pitch, but I do appreciate your candor. These are proven, widely used techniques for attacking, eliminating and preventing the recurrence of blowholes. Since it is so ea
