Dear TechNetters, a contract manufacturer has problems in controlling the soldering process after switching to forced gas (from infra-red). One idea was letting us change land patterns ("my experience: oval works better than rectangular"). Any experience reports, hints, literature regarding land patterns _and_ soldering process would be welcome. Any hints on process optimization we could forward to our contract manufacturer are also welcome (is there a "top ten faults in forced gas convection soldering"?). Thank you very much in advance.
