chips up to 1411 ( I have not seen a 1411 component yet, but 1210 is a good number ) in 8 mm, IC up to SO8 in 12 mm, IC up to SOL 20 fit in 16mm tape. This is just a basic rule. You may also find SO 20 in 24 mm tape. More important is the reel width,

We are experiencing some difficulties with reflow soldering a 1210-sized MOV with silver/palladium finish. The PCB finish is SAC. When inspecting the board after reflow it seems that nearly all solder is gone both from the pads and the component term

I'm guessing you're running small batches of boards on the MyDatas. We had the same issue with management when they decided to save on parts (not realizing it cost them more in time and more frustration for us). We had Agilis feeders so that helped.

@ Sr.Tech, Any voiding means that the part of the package under the void is not forming a solid thermal interface with the PCB, therefore it's heatsinking capability is reduced. With the drive for smaller packages with higher power handling capabil

Hi All, Can someone please help, I have a number of tall surface mount components that according to IPC 610 (8.2.2.3) are a fail due to the end termination not wetting at least 0.5mm + solder height. The components are very well soldered but the sol

Gary, Here goes for what it is worth. We store all of our SM reels in the SM area in proper trolleys (Mossmann-Tebbs types). They are stored by part number, which sets them into Capacitors by value and size. Resistors the same and so on with induc
