My customer just assembles it to the car. We want to use the silica gel to avoid moisture since the assembled part (clock) reach him via ship after 50 days. The electronic circuit board has no conformal coatings at present. We are working on that. Ou

We have an Electromechanical assembly (clock) that has a step motor on the board. This electromechanical assembly is assembled in a screw less plastic moulded casing. The plastic casing is neither air tight nor water proof. The board is with SMOBC+ H

Are you sure that the parts are bouncing? We had similar problem where diodes were placed very closely and occasionally nozzle pushed already placed part away (due to pick-up tolerance)...

Three ideas for you: 1) Make sure nozzle tips are clean. 2) Check coplanarity of leads to bottom of body. If leads are above body, it could be the are not contacting paste well. 3) Investigate static charge in the parts caused by the feeder or

Is your solder paste deposit drying out? Or if the paste deposit is small or there is insufficient paste then the tack between the device and paste will be poor so it can easily come out of the paste during its placement or placement of other parts.

What i have on the original 2 problem boards is the parts next to it are SOIC8 and placed using a 125F(.125" dia) 1 of witch is close and we have to Z zone it to place the SOIC last, the others have more than .02" clearance on all sides. The other

What we have had recently is a lot of larger thin (32 thou) thickness boards that have had issues with SC90 diodes bouncing off the pads in the final PNP machine. Our setup, universal instruments GC120 or quad beam 30 spindle lightning heads. This m

Hi All, I've been in the CM world for a long time and it seems like there has been little change in the packaging techniques used at the end of the day. Assembled circuit boards in small/flex volume are bagged or bubble wrapped and boxed up to ship

Wrap your Final QA inspection into your Final Test and call it a day.
