At work we use a system in which every customer uses a part with a phantom ( top level ) part and then under that we have more part numbers that are valid. So something like a surface mount resistor would be stored as something like. PPPPPPPPPPPP

Hi Patrick, thanks for the response. I might add some more information - we succesfully soldered some boards with the same settings of belt speed, pre-heat temp. etc. This batch of boards differs from the previous in a way that they are 4-layer. May

Hi davef, thanks again for that enlightenment. I'm just curious about what's happening with the solder joint of the said process. Again to add to my unending queries for now: So on top of that copper is a thin layer of lead-free solder composition

I started a new company that has a Testronics 504 AOI machine. No one knows how to program it, and they can't find the manual. So far I have been able to load a centroid file, and set the board size. However, when i load everything, all my parts a

Thanks for suggesting the GSM-1, Deni. There is a dealer not too far from us that has one in stock so I'm going to go check it out today or tomorrow. Got a few quick questions for you: 1. can you load cut tape onto the feeders, or only reels? 2. how

OK Sergey, looks like no one wants to take this on. I will give it a shot and maybe others will add their 2 cents. The answer depends on what you want to inspect. X-ray inspection is based on the X-ray absorption properties of the materials in th

As the article eludes to, you still need probe access to measure the pins with TestJet. One thing I wanted to add was the use of JTAG for use with Boundary Scan. Certain devices have JTAG capability, but not all JTAG devices are Boundary Scan compa

I have used the Quick ? from I don't remember what company. But it was a smallish machine ie about the size of a washing machine. The heat/cool cycle was about 30 to 45 minutes. every thing had to be properly sealed or you would loose vapour, this va

Good afternoon all, I have been trying to find a solution to a defect I just noticed. After stencil printing and smt part placement on the secondary side of my boards, I run them through a wave soldering system. All my components got soldered perfe

Hello Sid: i don't know where you bought the machine. the central support system is an addition part, it is specially designed to prevent the PCB board from bowing. i know that the wave soldering machine which made before did not include this useful
