Hi All: Thanks for the feedback. I've did a lot of surfing for more info and found there are pro's and con's to each side. One side with the customer P/N your customer service doesn't have to worry if the others bump their builds ahead of your an

Stefen- When looking at it from your perspective only it makes no sense to off-shore. The machines and operators are but a small part that goes into the decision to move overseas. The bigger picture is the fact the "entire" operation gets outsourced.

Have the SOIC tested by independant. Clarify as to weather or not you have run this board before. Check to see if the board has been rev'ed. Sometimes IC's are rated at a clock speed or by axcess time. Engneering on this board may be at the tolorance

This has always been a big debate on what is better. Few things to consider before getting into number of zones. What is the throughput and cooling requirements? Throughput is a direct relation to length of heating zone. Longer heating length

In 1995 we bought 4 Vitronics U520 reflow ovens with top heat only. We ran these ovens until 2003 for both curing and lead reflow with no problems. In 1998 we bought 1 U520 top and bottom heat and one U820 top and bottom heat and once again we had

Hi All For the past 8 years we have been screen printing paste succesfully using hard rubber blades. Over the past 12 months we have changed paste from lead to lead free, the board size has changed from 300x200mm to 120x90mm and we have also moved

SMT assembly, First, you must utilize paste otherwise the parts will not stay put. Do you have any leaded devices such as QFPs or SOICs? Dispensing paste by hand is very difficult and time consuming for these types of parts. You can either dispense

Assemblers often assume that the board and component suppliers provide them with clean product. This was not a problem when everyone used water washable fluxes, because the water washing used to clean the flux residues also cleaned the board and com

Hi Serge, First of all: "i HAVE to buy"...? Sounds like someone is twisting your arm to buy a piece of iron you're not really enthousiastic about... But on a serious note: I've been comparing some machinery myself (also with Pana and Siemens) and I

Does Serge need bacons or turkeys?? None of them?? Then let him think about which machine suits his requirements! Throughput, flexibility, large board handling, output derating across board size variation and component size variation! Future proof -
