You may have to use an adaptor board. A small board with one footprint on one side and the other on the other side. Do not assume that the pin outs of the two parts are the same. I have seen smaller parts with a different pin out than the bigger part

Just give them triple the price and they will love to make re-design. If you do what was suggested with the additional PCB, price might be close enough to triple.

Hi all, As per PCB design have to mount SOT 6PIN, BUT Customer requested to place the SC-70 6PIN component. I know that it's very challenging for this activity. Customer is not ready to change the PCB design. So we have to mount SC-70 6PIN Component

Part library is big enough problem. Whatever machine you pick you will be able to transfer XY, Theta coordinates as well as reference designators. This will help in programing a little, but this is all you will gain. all packages, vision algorithms

Hello Billy, We have 6 machines tied to a server. I can see where this would be a problem. Basically, the answer is you would need a package for every significantly different package that you are placing. I don't think you can just say 3 0805 packag

Everybody who uses basic "part-type" naming conventions for machine package codes will have this same issue unless restrictions are placed on who, how, and when the package codes can be altered. Some alternative methods to solving this problem: 1. U

Anyone can share experience on package crack for QFN package. This package is so sensitive to any external force. Any good recomendation on desoldering / rework procedure.

Hi, Thanks for the info. You mentioned about TQFP, how about QFN, which is leadless and one sided package compared to TQFP ? Actually, we are component manufacturer. Recently we have multiple customer come back with issue of electrical failure on par

Hi chs, What type of QFN or MLF package are we talking about? Assuming there is a middle thermal pad? Body Size & no. of terminals & pitch? What about your statement: "This package is so sensitive to any external force". Can you please explain what y

Hi, There are QFN 32,40,48 pins with middle pad. Body size are 7x7 and pitch 0.5mm. I means as compared to 2 sided package, QFN are easily damaged by external mechanical / thermal force. Phenomenon observed are mold cap open which further caused wire
