If you are using a low end hot air system IE: Weller, Hakko or Pace then your problems are with the system and not necessarily with your process. However process is important. We have found by inspection with an Ersa Scope (BGA inspection system) tha

I am not familiar with the ERSA system you talk about but wanted to let you know there is another company call PDR that also uses IR and no nozzles. the machine is pretty slick and easy to use and set up. We have found no adverse affects to the IR he

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

I too use to run Ersa machines. The new engineer has gotten me kicked off them because I know more than he do. we operators are on the machines all day, so we know more than than the engineers. They may be good on the computers, but we now the mac

They are expensive so you need to have a lot of jobs that take a long time to hand solder or have a ton of masking. Also look at bottom side wave soldering, if you are having a lot of defects, the selective will allow you to solder both sides in surf

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

Do you watch when it is doing the wave height test? Watch it and see if it goes up to the same spot on the test probe each time. If the test probe is dirty sometimes the solder has to go up higher on it before it gets detected. You might actually be
