I find that software is a quite individual part of the entire machine. Some programmers love to have at least 20 windows open at one time and others prefer to put all information on one single page. What appears to be easy for one, may be difficult f

A couple of questions to establish a baseline for when the check writers start asking questions........ How many of you have vision systems on site for BGA inspection? If you don't have it, do you do 100% X-ray, or did you just nail down the proces

Dave Many thanks for your very informative piece on SMT.com As we stand we have not yet 'seen' any problem. My issue is that we have ordered (LTB) a very large quantity of ASICS and our usage has taken a down-turn. We therefore need to keep the one

Hello all, I am having soldering issues with an Everlight component it is a TM4201/TR2 (Right angle IRDA with a 1mm pitch). The problem I have is that after reflow the solder joints look perfect, but during test we are losing 7 micro amps as soon as

Well it depends on what kind of oven you have. If you have a short oven, you are going to have a difficult time. You will probably end up having several different profiles if that is the case. We have 3 BTU TRS 212 furnaces. They are fairly long 8 zo

Hi Marc I too have been using a fully synthetic Motor oil on Heller reflow ovens for a number of years. In our case Mobil 1 5W-50. We have a field failure problem with some 1% resistors under conformal coating where sulphates are dissolving the si

Hi .. I have read with keen interest on the various replies on your query.. However, the most important thing that seems to be missing in the replies posted is reference to today's business scenario..which calls for a very fast ROI (return on inves

Hi, I have received a report form a board supplier, analysing the reuslts form non wetting problems we have been expereincing with their boards. I assumed it was due to the gold layer being too thin, thus allowing the nicklel layer to be exposed and

Use an "LCR" (L= inductance, C= capacitance, R= Resistance)meter. There are several name brands to choose from (Fluke, etc.) Hand held units are relatively inexpensive. In fact, you may consider having more than one available. Receiving inspection s

Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is
