Are you reflowing them and they are coming out of the oven bad? If so, what kind of oven are you using? What kind of LEDs? What kind of solder? Mass of substrate? Have you ran a profiler through your oven and compared the plot to the solder's spec

Russ, I still don't understand where you're coming from! The chipmaster is a closed loop system...it has a thermal couple. Also, I've got profiles on mine! If you're having problems with a loose nozzle just tighten the four set screws in the bl

Former company we use to replace No Lead BGA's by using dot dispense to apply eutectic solder to pad with same volume the stencil printer. Current company process removes bad BGA, wicks off solder paste then Hot Gas Reflows new No Lead BGA to bare pa

The best station I've ever worked with is a focused IR station from PDR. The station that I had was called a; "Lightmaster Pro". They have a different model name now, but you can see a datasheet for it at: http://www.pdr.co.uk/Datasheets/PDRX410-IR-

Good ol' general purpose, day-in, day-out ~$1k hot air rework stations are: * Pace ThermoFlo ST 300 Low Cost Hot Air Reflow System [ST 325 is digital] * Hakko FR-803B SMD Rework Station [FR-802 is digital]

THE IS A REASON ITS FOR SALE CHEAP THE DRS 24 IS BEING SOLD BECAUSE ITS NOT SO GOOD FOR LEAD FREE BGA REWORK IT CANNOT RAMP UP THE PCB AND PARTS AT THE SAME RATE BECUASE OF THE HOT PLATE.ITS A OLD MODAL AND LOTS FOR SALE AT $10K AS NO ONE WANTS THEM

We've used hot-air guns in the past to rework QFN's and DFN's. Cheers ..rob

Dear ALL, I Wish to know 1.which type of rework station is best compare to the IR or HOT air convection. 2.Which process plays best reliabilty on soldering after post soldering process. Pls, suggest ur best
