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 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

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

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

I have a through hole product that is currently built with HMP solder(93.5Pb,5Sn,Ag1.5). We then dip it in 60/40 SnPb to give a solderable finish as HMP tends to oxidise. We need the HMP as our Customers solder through reflow ovens. Some customers w

if a solder has over 85% lead its classed as RoHS complient because its difficult to achive the same melting point with anything else (298degrees). a few other alloys with a similar range are ; % % 266E266 82.6 Cd 17.4 Zn 271MP 100 Bi 280E2

Depending on the connector you should be able to use a standard cheap arbor press with some cheap home-made tooling. Standard arbor presses typically have a rotating disc with cut-outs, remove this and put a decent quality stainless steel block in it

The 1CA0A009 would lead me to believe that the PD's may not be as accurate as possible. If the PD is bad then every location that uses that PD will have about the same error rate. The 12040403 would lead me to believe the feeders are haveing trouble.

Hi I just would like to ask some assistance how to convert a line using a leaded process to a lead-free process? Is there a need for us to change any equipment? printer/reflow? Currently, we are not yet in full 100% lead-free process yet so most lik
