Hello Scott, We have sold modified 101 nozzles. They had a .25mm hole instead of standard. The customer ordered these for placing 0201s. Is it possible they were used on the 740 machine? Or maybe the 760? FredC

I would suggest creating a special reflow profile, heating the board up to 130C about 50 c below eutectic point (183C). Then applying heat to only the BGA, this will prevent thermal shock to surrounding components.

SN100C is the Nihon solder. I had wave solder the board using SAC. Then had to put on solder pot, which had SN100C (nihon) solder. I think I went upto 130-135 deg C.. Let me try cooking it to 150degC Thanks

The soldering handbook that I use gives a 'rule of thumb' for best preheat temps for wave soldering. For multilayer brds that are metal core it suggests 110 to 130 degrees C topside temp to get the best solder fillet. We do a lot of multilayer meta

Dear Lisa, as for current, we're using Sony SI-F130 & G200 machines. for my personal opinion comparing to Pana HT122 & JUKI KE2060, Sony machines are very delicate to handle. the precision is good, especially 0603 parts, but for maintenance-wise, it

Wolfgang: A snipet of information that maybe more on track that the previous babbling: The temperature limit for FR4 is 130�C according to UL746(?) Good luck Dave F

We agree with Russ. Your topside should be 100 - 130*C. Your 265*F is at the top of the range. Look here: http://www.interflux-electronics.com/Products/Fluxes/IF%202005M/TD%20IF%202005M.pdf#search=%22Interflux%20IF%202005%22

So you are suggesting to begin heating using a preheater only . . . then when the thermocouple under my PBGA reads around 130C, turn on a top side heater? Thanks

We use the flux Cobar 94-SEL with excellent results. It is a special flux for selective soldering process. When the temperature of the board with flux (preheating or during soldering) reach more 130°C, the rests of flux are deactivated (no more dange
