The part I'm having problem with is a simple 0805 resistor 0R the inspection is done optical not mechanical and 75% of the rejects rate has the message: one or too many bad leads found. and the other 25% the messages will give a Background or Contras

I can tell you that I have been involved in new process chemical introductions for 40 years. I have seen a lot of claimes and this is one of the best inovations I have seen. If I was not convinced of this I would not be involved. As for process impr

Good day, You are right. PanaPro system isn�t very easy to use; it�s rather complex system, but very flexible and very powerful. It has a powerful core together with a lot of useful software functions. For example build-in text post-processor, good

If you are running FR4 PCBs and not something exotic like Kapton flex circuits, I would go with the Dek 265 any day of the week. You will find that Dek supports the fully automatic printer much better than the semiautomatic printers like the 260, 24

Tricky question. 1. If you are using fiducials on the snap-off areas then try and have the tab adjacent to these. 2. In many instances your tab locations will be determined by the case in which you are fitting the PCB. You don't want to be filing dow

The NexLev connector is built in a stripline construction, providing a continuous ground plane for each signal contact. The connectors come as tenrow connectors with 100, 200, or 300 positions at possible stacking heights from 10 mm to 30 mm. Technic

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

I have never seen any industry standards for setting up an SMT assembly facility, but I�ll offer some basic advise. An ideal SMT assembly facility is one that is clean and well lit and has environmental controls to maintain temp and RH. Temp of 24C (

We have the same problems with cut/tape parts. But, we specialize in short-run prototypes, so I don't have much of a choice but to deal with it, and find a way to make it as easy as possible. We just demo'd a splice tool from Sierra Electronics (ww

I'm probably not telling you anything you don't already know, but a technique that's worked very well in the past for me is to methodically step through every part of the process and observe your boards being built, or take a scrap or simulated one a
