Does anyone how to output Gerber from Wintypon5 software? I am dealing with it first time and don't know how to do. BTW, I doubt it is French version but not sure.
Thanks very much if someone can give me a light!
I still remember the dialogue with our process engineer, Er won't be changed very much in the case of 1MHz or 1GHz in fact. You see, 58.7 ohm @1MHz = 60 ohm @1.2GHz. But as far as I know, the general imp tolerance in most factories are 10%. The difference 1.3ohm should be covered by the...
If you use it to calculate the IMP control, it goes well. But you'd better respect the PCB manufacturer's comment if they need to resize the imp track width to better control impedance. They always can better understand their own manufacturing truth than designers.
Just take a look at 3mil...
Your formula is seriouly affected by the actual manufacturing environment of your PCB fabricator. It is very hard to say and give you an universal formula. Generally speaking, in base copper 0.5oz or 1oz case, w1 and w2 won't have a big difference. But it comes to 2oz and 4oz case, there is...
expresspcb to gerber
The official way is that you give express $60 USD, they will help you to transfer to Gerber.
If you want to use it to make PCB, you can send to us. We have a sucessful exprience to make PCB in the format of ExpressPCB.
electronic parts +small quantities +china
I believe it is very easy to find any type components in China. Why not try to contact me? I can find tens of hundards of China suppliers who can offer STLC2150, no matter small or big order.
