good question Reese In addition what type of flux do you use? after seeing the board am pretty sure it's a no-clean but is the flux water based (VOC free) or solvent (alcohol based) Maybe one more question what brand and type of wave machine you use?

We agree with all of what Patrick has said. Hopefully your equipment is capable of the ideal setup you describe with no back flow until the product hits the wave and then back flow until the product emerges the other side. One other reason to strive

| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

We use these but we hand solder. The resistor is basically a wire inside the encapsulant. When we noticed the bowing, we tested about 200 that were on different CCA's. They were all fine. If they want to use these under the wave solder, be sure to lo

Hi there, I intend to mount some smt components on the soldering side of the PCB and solder via wave soldering equipment. We do not have a reflow oven to cure the glue. Does anybody have a suggestion what small heat cure equipment or system can be u

I am looking for sources of temporary peelable solder mask to mask/cover holes on a circuit bd that need not be soldered during wave soldering�..must have distributors in Australia. I�ve contacted some down here but they do not have products package

All y'll: I could use your input on determining when to skim dross from a wave solder pot. On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. On another hand, ov

I am looking for some design guidelines (length, width, spacing) for solder thieves which are placed behind trailing pins of wave soldered SOICs. I'd appreciate it if some one could direct me to the appropropriate reference. Also, has any one perform

Short term fixes can be: have the vias "plugged" with solder by the fab house. This works if your fab is HASL finish. Tent the vias with solder mask, top side only. You may get a flux entrapment issue in the vias with this manner. Long term fix can
