PB-free Hasl was not mentioned due to the following: 1)Equipment Convertion at the PCB Manufacturing side is expensive. 2)You are subjecting the PCB to Higher Temps than Std. solder. 3)Most PCB Houses are not going to invest in Two Hot Air level

Our facility in Asia wants to change their solder paste to a local manufacturer. I have recieved specs for this paste and compared to our existing paste spec, there is not really much difference in material composition. The Asia spec tests the paste

I'm using an EKRA X5 printer. My QC department has been rejecting boards for "fibers" in solder joints. After investigation, I have determined that the fibers are coming from the stencil cleaner paper. I'm using JNJ Industries p/n 5404EK paper. A

I have been getting non wets on fine pitch QFP packages on random leads during reflow process. I noticed that every time there is some flux residue left between the non-wet lead and the solder pad. No residue was not observed on the rest of the good

Hello all, Finally ready to run my first 14 up array and the machine picks up the part moves to the placement location, them moves to home and drops the part. The Z axis never moves. I do get a "run error 1" at about the 4th placement (if it was a
