Agilent TestJet Technology White Paper In the early 1990s, the testing of digital parts became problematical. Previous in-circuit test techniques sought to ensure a correct, functioning part by applying digital patterns, called vectors, to the input

Multi-part reeling for pick and place

I think we should shift this issue to the machine suppliers, requesting changes in the machine design, in order to keep at least the jobs of high mix, low volume in this country. We can only compete with low labor cost countries by increasing the lev

The Tesa company delivers Splice Tape for 8mm, 12mm and 16mm. Also special splice tape for 8mm paper tape and some splice tools as well. Siemens uses for large tape a 'staple' but might be patented and then cannot be used outside Siemens. (Staples

Hello Joseph, Sorry for the bad news but microcracking is a well known potential condition occuring with the SAC305 alloy. Microcracking is a condition being seen with many joints soldered with the SAC305 alloy. It is technically a shrinkage cavity

Hello AJ, The previous answers are correct; Sn has seen a spike in price ever since RoHs was implemented. Furthermore, the other alloys that have been used to replace Pb (because of RoHs) have also seen an increase in price. Sadly these material rep

250 tons/month) and, as it has been stated here, many customers have switched from SAC305 to SN100C but we are not aware of any customer who has switched from SN100C to SAC305. As the inventor of SN100C states, �once a customer touches the SN100C, he

Lead-Free Wave Defects

Hello Amol, I continue to be amazed at the surprise engineers have on discovering that a non-eutectic alloy such as SAC305 displays micro-cracking and rough joints in a soldering process. There was a reason the electronics industry chose to use eutec
