Some Selective wave solder jig designer milled down the jig in one depth which is based on the thickest part on the bottom side of the board. This will create problem on the warpage on the jig due to the heat coming from the wave soldering machine. I

I'm often in a position of needing to get accurate answers regarding PCB technical information in a hurry. As this is the case and I am new to the industry, do you have any tips for fast web-based searches or can you recomend a sort of encyclopedia

We are currently running boards with resistor paks on the solder side of the board introducing these to the wave solder. We cannot get rid of shorting between the leads. We are using a water soluble acohol based flux. The option of going to selective

One thing I forgot to add about the globs of solder on your bottom side SMT components after wave soldering: The excess solder is likely reducing the reliability of these components, because of the difference in CTE betweeen the ceramic base on the

You can make up a plate over lapping the tape exit guide and to the right up to the nozzle changer. It should hold three standard size Jedec trays. I used the bases of two old vibratory feeder. No matter what you do, you should use strong magnets to
