We use to use a malcom mixer but found it caused problems of solder/flux separation. This may be causing you problems. Earl Jr

Is just me, or too many "soldering issues" have been observed lately? on this forum... could be a ~90% components "backwards/compatible" in both leaded/lead free process?

I heard of a new technology from OMG that helps extract more solder from drossing, I believe. I don't know where you're located, but my OMG contact is Jim Gilbert (Jim.Gilbert@omgi.com) in case you are interested.

Sounds like a good challenge. What is your interconnect bond method? Solder Paste, Pre-Form/Liquid Flux or Paste, Assuming your using solder. Reflow method?

Some solder paste formulations can be frozen with no effect. Other formulations ... not so much. Can you compare this questionable solder paste with 'known good' paste of this part number in a structured test?

Hello Again...SMTNET....are there rules to determine which small BGA devices are Dip Fluxed or Solder pasted? What drives the decision? Obviously the device's pitch has a large bearing on this decision. Any and all comments or experiences would be ve

Thanks for the comments, I will take the rocks out of my head, throw in a little lead from my ___ and save some $ on solder........... Seriously, will look into some of these ideas, or some iron weights/slabs from metal store P

Hi, I am having a issue that SMT nut drop after reflow. The solder height all in specifications. Had tried adding flux inand the solder paste. But shows no improvement. Is the nut easily oxidize? Can anyone help me on this?

Do any assemblers use AVX FLEXITERM components ? Anyone experience any instances where the devices look to have soldered well, but then when handling the pcbs, and maybe with a little bit of pcb flex..the CHIPS just drop/pop out the solder fillets ?

| All y'll: I could use your input on determining when to skim dross from a wave solder pot. | | On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. On another ha
