call me picky but doesn't hydrogen combust? maybe soemthing you could do is look at your process and your products and decide if you actually need to run in N2. Yes ok I can hear the crys now but seriously, for the vast majority of things if you have

Intermetallic growth is a diffusion process, the thickness of the intermetallic is given by: z^2 = (Do)(t)exp[-Q/RT] Where Do (m2 s-1) is the diffusion coefficient, T(�K) is the temperature, Q (J mol-1) is the activation energy and R (8.314 J mo

Let's think about this, there former filed service engineers. I bet they got out of field becasue of being laid-off. Typically the NON-Performers are the first to go. Hint hint.....former field engineers! Quad 4C's when they were new to the marke

Hi Mark, There are many tools available for measuring solder paste height. Most machines use laser as the basis for inspection while others use structured white light. If simple height and width inspection is all that is required, you can look int

Shameless? In APE's experience not so - air velocity/power is extremely important in carrying energy to the board and close loop control of that energy is crytical in maintaining a controlled environment - if a machine design requires that air is for

From my perspective, regardless of the size of your company, you want the best value for your money and latest, greatest in innovation. For pick and place, while Mydata, Siemens and Assembleon/Yamaha all have some cool and worthy concepts and worth e

Electrovert has a new nozzle design called UltraFill. It was designed specifically for Pb Free applications and generates about 40% less dross than the previous Lambda design. UltraFill can of course be used for Sn/Pb alloys. The name UltraFill is fo

This is highly dependent upon your board, vision inspection, part rotation, part type, layout, number of P/Ns per (1 pers or 100 pers) feeder layout, optimization, nozzle changes, etc... all have significant impact on placement speed. I find if you

Hi Peter, You certainly have a selection of kit. We use 2 CP6's & 2 GSMs per line, and that balances pretty well (sometimes one of the fuji's is idle though - but we can live with that). When we had S20's we found 2 of them roughly kept up with a

If you have control over your design (as in an OEM) ENTEK can be a managable alternative. IF your like me (a CM), you get one of everything ever imagined. There has been much ado with ENTEK. Not every product is apropriate. For instance I have cu
