There is none, since we don't know your part or temp being used. A heat gun CAN be used to remove parts with no damage, if its controled. You need to look up your part on the manufacturers web site, find the process data (time/temp)the part is desi

Comp is relay. I've pulled the spec. Max 240. Using Leister h/g with manual temp settings from 1-6 (20 - 600C)set by the operator. Gun was set to setting 4. They are using the heat gun to reflow the solder after SMT but before wave. High fai

So others can solder the same board and part but you can't. Dipping the legs in flux doesn't help. Then it's either your pre-heat or wave. Measure your pre-heat and compare to others or flux mfger. Do you have chip wave or something like an Omega

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Is there anyone that makes a pick and place glue dot for surface mount chip components (B stage epoxy dot in a carrier tape)? Thanks, Rich

RS sell a heat cun that is fully temperature adjustable buy one of them and pre set it to the right temp then put a calibration sticker over the control.

I cant touch the pre-heat as it would affect all other products or so i am told by the Qaulity manager. Maybe they think i am Mickey Mouse and the pcb�s jump around the factory like a scene from Fantasia :) if this was only the truth.

Heat guns used improperly will definitely damage components. You must have a controlled heat gun that can be set to the max temp you want pb =215C max, Pbfree maybe 240C max. This heat gun must not be able to be adjusted or you must have total trus

Your Quality Manager won't let you make changes, yet you get blammed for process problems? First, you need a change in management. Second, if you can't change set pre-heat temps, change the conveyor speed. Slow it down and see if your joints loo

Relays huh? I can tell you from previous experience that relays are not a good heat gun candidate. Did you check how long this part can withstand the 240? I do not know what the 4 setting is on a liester but it is probably well in excess of the 24
