This is not something that we'd expect to see on NiPdAu finished leads. Help us understand the extent of the problem better. From your picture, it looks like a band of copper color with black on the outer portions of the copper color that bleeds int

We use a Charge Plate Monitor (CPM) tp monitor the balance of our ionizers, according to ANSI ESD STM3.1. Maybe you could use a CPM to assess the ionizing radiation in your plant. The more we think about it, we feel you could use a Geiger-Mueller (G

Its not likely your air quality that lowers the test solution's resistivity. Maintaining 60 M-Ohm requires almost constant circulation through DI resin beds. Just natural CO2 (Carbon dioxide) absorbed by the test solution will lower the resistivity

we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,

you cannot swap 0-3 only 0-1 or 2-3 they are not the same euro cards. they function very diffrently. if you look you will see there are more chips and circuitry on one set. there are 2 w/red leds and 2 with green leds. at least thats how they soo

Can you have an outside vendor source it for you? Kind of like an "in house store". Besides paste, they would also supply you with all your other "dated" material. That way you only get charged for what you use. Then make sure your operators chec

It depends on the usage , if it is regular and steady, only order when needed , we only order 2 jars when the last one is taken out of the fridge.One jar would last us about 2-3 weeks and it stays on room temperature. Ofcourse , you need a realiable

Has anyone seen this? - We have a new smt pcb with 2 x LF356 (Op-amp) IC's on it (plus others). When the pcb is flexed the O/P of each IC changes by �2mV DC. i.e. the board is acting like a strain gauge! There is no oscilation and when I replace th

Thanks but we have QFP208 package here that after the reflow soldering during to the bad coplanarity of these devices some pads doesn`t have enough solder or not soldered. so we decided to use a qfp nozzle that can be placed on a QFP pads and use a

If you have coplanarity issues on components that have not been assembled yet, check out an equipment that will help you resolve the lead coplanarity problem before you load them in your assembly equipment; I know that Fancort sells an equipment for
