Hi, I was wondering what is the difference between MP and NO at the end SMT part number. I tried to look into it but could not find anything promising. e.g I have a resistors with part numbers 0603-NO and 0603-MP and 0603-RES. What could be the diffe

Started with a 1 part shield and we had an 0201 tombstone due to the pad design. We changed the pad design but the customer wanted to be 100% sure, so we moved to a 2 part, adding the lid after verification. We also trialled the original 1 part c

I have only seen ceramic PCBs a couple of times. Make sure you run a temperature profile on a PCB. But you should do that anyway. Other than that I don't remember any other issues. I can't remember how they were panelized You might want to check into

Reflow temperature recipe: Keep ramp rates below 1.5 deg. c/second. Ceramic is such a good heat sink you will need a slow profile by today's standards. Handling: Do not drop ceramic boards Handling: Wear gloves ceramic can be very sharp General: T

Please take a look at the model DEN-ON RD500V series machine , it can handle 700 x500 mm (28" x 20 ") and can also be customized for larger PCB. The company is quite reliable (55 years old) and makes very strong equipment. http://denondic.co.jp/en/
