Major Japanese OEMs investigated numerous lead-free alternatives, including alloys containing bismuth and/or zinc, such as Sn/Ag/Bi/Cu, Sn/8Zn/3Bi and Sn/58Bi. However, over time, the Japanese industry has moved toward Sn/Ag/Cu alloys. The Japan Elec

We do not know how your KIC2000 calculates slope. Here's an approach to calculating slope: * Subtract the lower temperature from the upper temperature. [Temp|upper-Temp|lower] = Temp|change * Subtract the time when the lower temperature was measured

The sampling rate on the KIC software can be changed by the user. The default setting is a sample rate of 60 seconds, so that, every 60 seconds the "old" measurement is subtracted from the "new" measurement to calculate the slope (i.e., start temp i

Your customer is correct. Components should not fall a board during a reasonable drop test. A shear test poorly represents a drop test. A drop test represents a drop test very well. If you want to proceed with shear testing, search the fine SMTne

You state that you need a washer for �pcb washer/cleaner for misprints etc� Is it only for misprints or is it also for post-reflow de-fluxing? I would not suggest that you utilize one machine for both applications. Misprints should always be cle

First, don't get too excited about the thermal capabilities of conductive epoxy. An epoxy like DuPont CB-100 increases the amount of heat conducted through the barrel, but many over estimate what it can do. Calculations show for a 0.020" drilled

We have a DEK 260 with a intermittant table align stepper motor problem. The machine will work fine for awhile and then one of the table align motors starts either moving hapazardly in small increments back and forth or vibrates as if it wants to mov

Lets face it guys, its happening and its all related to greedy profit merchants, other companies are simply following suit to stay in business. For 1 UK worker i can get 3 workers in Italy at the same price. If i choose to outsource to China, i get
