Before this wave solder pallet salesman blather gets too far out-of-control, let�s stop for a minute. The three major approaches you have are: 1 SELECTIVE SOLDERING: Using: * Specialty wave soldering machine to solder specific areas of a board * P

Adding to Mike's comments. There are two types of selective wave soldering machines. * Chimney type, like the AirVac and Wenesco that Mike used. They use a boot to funnel the solder to the component to be soldered. * Programmable head type [ie, ERS

Adding to Dave's comments, suppliers of selective soldering machines include Air Vac and Wenesco. I've used both, to solder and de-solder larger thru hole parts, such as connectors and large IC's. They are best suited to lower volume applications, an

Steve Often solder mask is the only solution but in many cases there is enought space between smt and thru-hole to utilize a component masking wave solder pallet. The advantage to a pallet is consistancy of results and excellent protection of masked

Thanks for all of your suggestions. Since there are quite a few options, the selected method will depend on volume, tolerated cycle time, ROI, etc. I believe we will be dealing with relatively low volume, so I am going to investigate the selective w

I agree with EMC based on what you described, and they build good pallets along with a few others, a small word of caution is that pallets are bit expensive typically several hundred dollars or more each. So if you find that is the road you go, be s
