I'm with John. Back in the old MIL-2000 days, the pot temperature was 245-275C (475-525F). Now, 240-260C (460-480 F) is more accepted for eutechic (eutechicish) solder. My2� Dave F

Hi, I attach the termocouples with high temperature solder wire, at the QFP pins.Other thermocople I attach at package with high temperature tape.

Hi Tim It sort of depends on the solder alloy being used and the particular assemblies being soldered. If you are using the usual 63/37 alloy I would consider 500 to be a bit warm unless the assembly required it. Some alloys would require a higher

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

Dear Pro, Pls, increase temperature up to 255ºC and considering solder's profile. Good luck

How are you attaching your thermocouples to measure the temperature of the lead/pad connection?

I would go with the BGA profile requirements if the other parts MAX temperature allows it.

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu

Well, since you've gotten no takers, we'll launch in to this with careful analysis and introspection, fully aware that we're likely to get 'blasted' for any number of reasons. The most critical parameters to monitor for proper wave solder machine pr

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f
