We use a "McDry" cabinet for humidity control of opened, moisture sensitive parts. Relatively cheap and works good. This cabinet is installed right on the SMT line. Check out: http://www.seikausa.com/products/mcdry/

Hi Hannu, Just out of interest, are these big, heavy transformers, where the weight of lead in the solder will be less than 0.2% of the overall weight of the dipped part?

Hi Hoss, I was speculating - there are others out there with more experience in this field than me, who may know the definitive on this. I've heard rumours on transformers but nothing concrete. But I was guessing that the transformer (as a whole)

Hi Pat, And thanks for the sympathy :) This thing with ultrasonic transducer, is it something tried and trusted or is this a new idea for improving the wetting behaviour of leadfree alloys? This is completely new to me, can you please elaborate on

Does any one have a picture of a unversal stencil adapter for a SPM printer? We have stencils for Dek machines that are 25" by 23"wide that we need to turn 90 degrees to be able to center the pattern for the spm printer.Or do you have one for sale? T

Just went through this with a customer. Removed BGAs and noticed discolered pads at some locations. It was determined that these were open connections that had some type of flux migration between the ball. They also took solder readily. This may

Bad cleaning practice is suspect. It is believed that W.S. flux was used to solder adjacent components and then hand cleaned. This is not definite but it is pretty certain.

could there have been a solderablity issue with that pad to begin with, allowing the flux in (from improper cleaning of adjacent work) to expadite an error may have happened later down the road?
