Hi DaveyF, Thanks You see, you proved my point, with piles of more information than I gave. Based on Application rather than design and manufacturing specifications, a lower IPC class can out perform another. So our starting Poster must look at t

Hi, This is an interesting point. I use Koki paste from Japan, and it's wonderful, however what properties of solder paste would make it "anti tombstone" paste? How does led free effect tomb-stoning? That would be interesting to know. We might go

We are a mixed volume facility and we are doing our utmost to achieve 55% utilization on HSP's (UIC 4797's and 4791's) We are basing this on a world class metric. I am wondering if anyone else out there is measuring utilization, what sort of result

Is this setup charge the cost of purchasing the required materials? I left that out of my previous post. As far as manufacturing cost, usually they add up the cost of machine time (leased or owned), operator time (wage based), and the size of the o

Hi, No Major issue using lead-free plated components in tin-lead as long as Sn/Bi is not the finish. I think some customer might be worried about low melting phase. More voiding may be seen in case of ceramic capacitors used with tin-lead. It is

How can one go about defining the complexity of a PCB for characterizing reflow profiles A large balanced board may be easier to profile than smaller unbalanced board ? Any ideas how to define an index to calculate the complexity based on size,weig

everyone made good observations in the arena of improvements. being rather pessimistic today, I'd like to say the one core area of little (if none at all) improvement is the over-reliance of human (aid/non-aid) inspection of SMT output soldering de

I just want a forum to track the bad apples. They are out their and people need to know who they are and the consumer should be fully aware of policies before you buy something. Sometimes they are unclear or the sales engineer tells fib. GenRad does

To us, time above liquidous plus 20*C is more important than the 60 sec [er what ever] above 183*C [which we think is meaningless] that the fine solder paste supplier suggest. Based on what you've told us and lacking any failure analysis, we'd gue
