ENIG finished is recommend. But the price is a little higher. For the PCB, I recommend Elecrow PCB service. You will see the PCB fabricated there is really cheap and the quality is really good.

Hi Syed, I'm a PCB engineer from China. First:Immersion gold surface finish is the best for PCBs. Second:HASL(Lead-Free HASL) Then:HAL(with lead) The cheapest surface finish is OSP(After 15 days will be oxidized)

Anyone have any pointers on how to measure the purity level of the gas supplied to Selective Solder machines? We use both bottled gas and also have an N2 generator and would like to confirm that both are performing similar.

I find that Elecrow provide PCB service at really good price. http://www.elecrow.com/services-c-73.html Is there anyone used this PCB service before? Hoping to get some feedback of them. Thanks.

Hi, does anybody know the steps for manufacturing a 6-layer PCB? Let's say we have 1 core and 2 pre-pregs. Thank you, Enrico Migliore

Have an external oscillator circuit contact the LED pads or a nearby connected pad and only apply power at say 1V and measure the frequency of oscillation of your circuit through a buffer stage. regards sarason

Does anyone know if theres a way to program a SOT23 or SOIC-8 with a pick and place machine on the fly? I have a pair of Mydatas if anyone know if they have the option

its in a standard SOT-23 package, designer suggest using a Microchip Universal 6L SOT-23 Socket Module (AC164321), but its no going to be manufacturing friendly

I don't think that the manual has ever been converted. I have some procedures that may help you. If you have questions or need some information get my e-mail at my website @ www.precision-repairs.com Bob
