0402 wave soldering

Electronics Forum | Wed Jan 07 07:50:24 EST 2009 | ludee_circuits

I think so. My customer once assembled resistors 0402 ,by Glue+wave soldering process. But PCB must be printed soldermask bridge between 0402 SMD PADs, otherwise you would encounter short problem. Sorry I don't have any comment for recommended footp

Blowholes during wave soldering

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

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

I sell wave solder optimizer in Philippines. I have sold many of this optimizer system. It cost less than US$10K. Most of my customer is happy with the performance except for some issues from customers like LCD not yet colored, uses RS232, upgrades

I have problems with blowholes during the wave soldering process. I already find out that the stock time between reflow and wave is the most important. The longer the boards are in stock the more blowholes we have. We don't have a climat controlled

KRIKIES! If that wasn't a sales pitch, I don't know whut was, me lad. Optimizer is good for DoE's and process characterization, but no substitute for the artform that is wave soldering. When me lads here in Purchasing get PCB's from all over the w

hello guys ; we are using some standard selective wave soldering unit used in lined ; the drawback of a such machine is 1/the speed which is quiet low (the board is coming on position through the conveyor, then the head delivering the solder moves s

That's just dross. If you have nitrogen blowing over the wave, you could reduce its flow as it tends to blow the dust everywhere if it is set too high. (on the other hand it might reduce solder quality)

Fine pitch wave soldering

Electronics Forum | Thu Sep 14 11:56:47 EDT 2006 | russ

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
