Huh, Are you asking to keep SMT and a cleaning unit for the boards in seperate rooms? That is not needed if that is what you are asking. But, I dont know the size of the room you are referring too so I dont know. We actually have our wash in the same

I've been trying to reach Needham's Electronics in Sacramento for over a week. Their website (www.needhams.com) appears to be dead, and when I try and call them, the call won't go through. (I get a fast busy signal). Has anybody heard anything? Have

The problem is there wasn't any reflow when the board went through on the bottom side. Even if they didn't fall off becuase the temp was set low enough, while running the top side, the fact still remains that there wasn't reflow on the PCB pads to be

The cable required for the Thinline has to work as a true RS232 interface as the unit uses all the capabilities of RS232. You will have several problems with substitutes. These cables (part number e00-2787-26) are still avaliable from ECD, the home o

We have measured the temperature of CSP solder joint. The peak temperature is 232oC and the wetting time above 217oC is 30s. But we use leaded solder paste instead of lead free solder paste. I doubt why no crack of solder joint was observed after cr

We just started having board warpage problems with one of our suppliers. The product has been in production for some time with no design changes, no material changes from the board supplier. Someone told me once that if the PCB cure was not corre
