I think what Chunks meant is... TOOLING = THOSE POTS So basically, if some of your SMT or Through-Hole parts move around via a redesign or a respin, you will incur tooling costs (TOOLING is "THOSE LITTLE POTS FULL O' SOLDER.") When you're research

Dear all, As we know there is a high risk of reliability issue due to lead contamination during mixture of NLF component at LF wave soldering process. But we have the following feed back from one of our customer as follow: Concerning the risk of m

I think the main cause of this condition is #3 because both #1 and #2 never change from board to board, these are identical boards with identical BGA revisions. These BGA's (as stated before) are about 3 years old.. I don't believe they are lead free

Thanks Cmiller & PR, I am warmed to hear others are doing this sort of thing.......like all inovative ideas, you often stumble into them. As far as im aware the ERSA dual Pot is the only machine avaiable on the market that can do this sort of thing

forgot to write, what config of machine do you have......? single or dual Pot / Highspeed.....?

We have a dual pot machine. The fluxer is not the slowest part of the process on most boards. However, we looked at running boards that had many hundreds of TH leads that we currently run through the wave in order to try not to buy a wave for lead-fr

If you do not have a lot of TH joints there are some advantages. No boards "submarined" in solder pot on wave. You can solder the bottome side SMT parts rather than epoxy them when the parts are put down. This should reduce SMT defects and missing pa

We have 2 dual head Versa-flows in line. We use them mainly for doublesided reflow jobs that have connectors and axial parts. I have about 15 jobs currently running on them. The advantage of having 2, is some of our boards have through hole on 1 side

PS, sorry for any confusion, ALDSMT and CMILLER are both me. ADLSMT is my user name on SMTNET and CMILLER is me, cmiller@adltech.com I usually use cmiler to reply to stuff as if anybody e-mails me it makes more sense. adltech.com is a work in progr

If you are talking about smt components I'd say absolutely not. If these are through hole components I'd say possibly (if they are in rows, and not a whole lot of them). The machine is slow, but the quality is great. Creating a wave profile takes abo
