Never thought I'd hear myself say this (& I will punish myself later). Whatever you do, don't buy an AP25, CP4 or IP2 for starting out in low volume. 1) You will need a LOT of space 2) You will need a very good constant air supply else the AP25 wil

Hi, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB

Dear all, As we know there is a high risk of reliability issue due to lead contamination during mixture of NLF component at LF wave soldering process. But we have the following feed back from one of our customer as follow: Concerning the risk of m

I agree with all the prior postings! But I have some additional thoughts about this. If there is a build up of moistures (% humidity) inside the pcb; before you reflow the pcba; then you will have the result out of the oven, just as you described. My

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

Hi, We are currently selling a MYDATA, and several buyers are interested overseas, but we did not know this can happen. I think the best thing would be to spend the money on the air ticket and travel to check out the machine. It's not much and if

Hi, We are not based in the US at all, but the US PCB manufacturers are the only ones that combine good customer service, the ability to product rapid prototypes without huge setup costs, and meet deadlines. As the global electronics market has chan

Q1. What is recommended viscosity standard? A1: There is no standard. ASTM D4040-05 "Standard Test Method for Rheological Properties of Paste Printing and Vehicles by the Falling-Rod Viscometer" is a test method that might work. For more, look her

I suppose it depends on your layout software. My weak recollection of what PowerPCB does is allow you to set up rules as far as spacing and where parts are placed, then you run the rule check, er something like that. As far as "Also what I"m thinkin

There are many rules, but balance is the key. It all depends on your processes, type of equipment you plan to run the panel through, as well as the type of components going onto the board. If your single up circuit has 6 thru-hole caps, 5 connector
