1 um". Some PCB manufacturer is telling me that this specification is not feasible in production. I would know if this position is due to the equipment (or process control) they have, or if in effect is not possible to satisfy my requests.

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

We are performing testing for lead free connector finishes. We want to run solderability tests on a series of lead free connector plating options in a series lead free PCB's. I need some advice on the most popular lead free PCB finishes. I am aware

Specifically, what element of the bare board is blistering? Tg of 140 could be acceptable. Search the fine SMTnet Archives for background on decomposition temperature [td]

I have two industry leading customers that have specific requirements for components to survive 30 seconds above 230C. In one case I have a custom ASIC that is heat sinked on the die (to the PCB). The sink pulls heat out of the lead frame very effi

There is no specification for lead-free HASL. You can use any lead-free solderability protection that meets your customer requirements. Use IPC-9701 �Performance Test Methods and Qualification Requirements for Surface Mount Solder Attachments� to ass

Hi Jose, such a process is possible, but you need to confirm that the PCB material has high Tg. In additon, you need to re-look solder paste printing parameters and make required changes in stencil apperture design for optimum solder volume. Just a

Q1. Can anyone tell me if there is a procedure for storing raw PCB's? A1. Yes, there are thousands of procedures for storing raw PCB. Why so many? Everyone writes their own procedure. Generally, they say: * Boards require individual separation and p

Sure, to be a true lead free enviroment all components need to be lead free or fall within the specifications of lead free as defined by the RoHS Directive. What I am doing is starting stage 1 of our journey. Layed out it looks some thing like this.
