Re: Quantity of dross and type of flux

Electronics Forum | Tue Nov 21 22:15:59 EST 2000 | Vince Whipple

Mohammed, The first suggested place to start with your question would probably be with your flux Mfr. Push them! The quantity of dross is effected by several factors: The higher your solder pot temp., the higher your dross level... but don't go too

Dross produced, are we in or out?

We would need more info to answer. How many boards get run between de-drossings? How many days between de-drossings? Are you removing dross only or some good solder with it? Jerry

Eric, We also have a UPK 650C. Our machine was configured for N2 and using the ConTour nozzle. If you're using this nozzle without N2 you're creating tons of dross unnecessarily not to mention probably getting tons of icicling. We found out the h

Hi, I am curious to know who manufactures kleenox for de-drossing wave solder pot. I do appreciate a contact/telephone info about mid-west distributors. thanks MP

Blue-Film on surface of leadfree Pot

Electronics Forum | Wed May 30 10:09:39 EDT 2012 | brettrenishaw

Recently we have noticed a purple-blue colour film on the surface of the molten solder. It can be cleared when de-drossing the pot. The pot will normally go a yellow/gold colour before it turns purple-blue. Is this most likely an oxide of the tin or

Micro Solder Balls and Vias bridging Issue

Electronics Forum | Tue Mar 03 09:29:48 EST 2015 | rgduval

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

Solder Saver ??

I don't know why anyone would even want any of this stuff since you get paid for the solder that's in your dross anyway. The way I look at it is that it's really a GOOD THING to have some solder come out with the dross while you're de-drossing your

Steps to Convert SAC305 Wave Solder Pot to SN100C

Electronics Forum | Mon Nov 10 22:15:53 EST 2008 | fctassembly

Bob The actual process for converting from SAC305 to SN100C is pretty painless. Basic steps: 1) make sure your solder pot is at temp 2) de-dross 3) pull pumps/flow duct(s) and clean 4) purge pot of SAC material 5) remove any remaining dross/alloy i

Lead vapor

I think it is a good idea to "waste" money on this analysis. Especially if you phase in a SAC wave alloy. Silver is not toxicity free....and lead free waves can dross 3 to 5 times faster than SnPb alloys. This produces a greater potential for airb

Hey Dave: At our facility, we use those masks that filter out particulates. Our safety department requires all wave operators, maintenance, and even wave process engr's (like me) to have these masks checked every 6 months for proper gasketing, filte
