Good question, here is the short answer : The problem is that dry storage is not the same as a bake process. If you want to bake saturated components, this should be done at higher temperatures. The IPC/JEDEC standard provides a table with bake temp

Dear Mike, As you might have noticed from the labels on the dry bags, the maximum floor life is specified by the component manufacturer and it can range from 1 year (level 2) down to a few hours after mandatory bake (level 6). This limit is based o

I admit, 16 mil QFP printing is very challenging but if all your control factors (print speed, etc...) are setup correctly (through DOE) extremely high yields can be achieved and more importantly a repeatable and robust product will be manufactured.

Folk's, I've been running with the datapaq system for about 5 years now. I have been using it on both reflow and on wave, the only issue I've ever found is that you cannot predict settings for wave, but then you can't do that on Kic and I don't thin

Hi Kerry, I also am glad that we have the opportunity to discuss the EPA �certification� with regards to equipment and chemistries. I also have contacted the EPA with specific questions concerning the program you are promoting. The EPA responded t

Let me put my two cents into this argument..After being part of many extensive studies conducted to determine the benefits of solder paste inspection, there has never been a case where the customer concluded that paste inspection (Height or Volume)wa

You've told us nothing about your situation, process, boards, or anything!!! If you leave some boards with very fine solder connections on the shelf for a cuppla years, the grain will become coarse. What do you mean when you say "grainy"? What is

Of course recognize off the top that I have a certain bias :-) - and the choices are somewhat limited if you are looking for off-the-shelf product. There is also NO independent agency that I know of (i.e. an electronic training "Consumers Report")

Consider using a roll solder with a flux that well matches the residues you can accept to be remaining on the board when you get finished processing. Many people use a no-clean flux cored roll solder for such operations, because they don't want to c

Dave. F. Hmmmzzz.... Thats interesting, coz as a contract manufacturer, we try to optimize processes asmuchaspossible.... simple...yeah! that's the word "Simplify".... We found that if you layout a production line, assume x10 operators, and one si
