A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Hi all, Need advice how to fix RJ45 short issue after wave solder m/c .Few actions taken to resolve this issue but the outcome was inclusive which was 1. Modify wave pallet 2. Change conveyor setting from 0.8meter/minute to 0.7 meter/minute 3. Clear

What is the actual function of the shortwave IR in the wave machine process? Is it just another heat source?. i know it can apply a lot of heat in quick cycles and has ‘penetrating heat’ but is that it? seems a bit too simple.

What is your setting on screen mask printer, stering solder paste, profile reflow etc?

What pitch IC? Perhaps a nickel stencil will work. Are your board FR4? Warping the board could play a major factor in solder shorting.

What is the part designator? A lot has to do with that. Also, is this a double sided reflow board. Perhaps you need to change your process to accept two heat cycles simultaneously. Solder thieves should work. Check the archives.

You even try out control/cut the connector lead length & turn the wave pallet loading direction?

Yea you gotta love those airknives. It may not work in this application if the shorts are present at the trailing edge. I have several boards that are using conns with pins at .050" centers and they short. The protrusion is .030" to .040". The shorte

Hi all, * Defect : termial to terminal touching btw two melfs body that created short circuit. * Clearance : 0.8mm btw two melfs body. * Size melf : diameter=2.4mm to 2.7mm, length=4.8mm to 5.2mm * Stencil opening : "v" shaped to minimise component
