Hi David, we used the following techniques in high volume production, depending on the type of flexi-board: (all were in milled pockets in a durastone pallet) 1) Kapton tape top & bottom 2) Spray mount & samll amount of kapton tape (you only had

Hi Jorge, The success of such production purely depends on process control. One needs to first understand the board layout in detail, and evaluate any critical components for their temperature handling capabilities. Remember, you are dealing with com

Sai: I can't amswer your questions, but I can give you some leads to people that may be able to help you. Below is a list of companies that deal used equipment. Some refurbish equipment, others turn the equipment from seller to buyer. Good luck.

Hi, There are a few different types of CP6 which I think the main differences are on the board loading side of things. To briefly answer your questions: 1.What is the actual CPH you are getting during production. There are a lot of variables to c

Tell them every action taken with the boards carries risk of damage. Process steps that don't do anything should be avoided because they carry the risk of causing defects. Even inspection causes the occasional defect, and board handling in general s

I would suggest that as well as repeatedly inspecting the same board and looking at the standard deviations of the measurements, you should perform some form of accuracy test either by measuring a known glass plate or by inspecting a board at 0 and 1

| Hi, | | For hand placement you should see about 150-200 ppm of errors (solder, placement, values etc) on a board populated of types such as 1206, 0805, SOT, Tantalum etc. . As for solely wrong components (component at wrong location) you can usual

We use a no-clean lead free paste with our manufacturing floor temp 70-75F and humidity 20%-30%. We have found that if the time from pasting a board until it goes into our reflow oven is less than 4 hours we have no problems. If it is greater than

Hi, We are currently having issues with hand soldering High melting point solder wire. Can anyone give a few tips. We are Preheating boards to 120 deg C and using soldering irons @ 410 deg C. The quality is ok but the ts taking 20-30 seconds to c

| Mario: Interesting analysis. What does "Hand placement versus wrong component should only ave. 20-30 ppm." mean? Is that a subset of errors? Thanks. Dave F | What I mean Dave is that if you have a good (well actualy a great set-up) with all t
