Hi, Anyone have the DRS25 rework machine and use it for lead free BGA's? Anyone upgraded their DRS24 to a DRS25? We may pay to upgrade our 24 to a 25 to improve our Lead Free BGA rework process. Thanks, Rob

Agreed, if your process is the same than most likely you received in a batch of lead free BGAs that are supposed to be leaded. Happens to us all the time and vice versa...

60% ratio would be great start. that is what we typically shoot for with all leaded for the most part. 25 mil diameter in a 40 mil hole, works great for auto insertion as well Russ

Paul: If your customer "resolders suspected IC lead(s), problem goes away" - It's not an 'black pad' issue. You need to improve the way you solder this product.

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

Anyone doing this, successfully in a robust process without any touch up required? Is it even possible? I use to do with in a leaded process.

Hi, I was wondering if any of you operators/users have experienced any reflow solderability issues with any of the ATMEL QFP components with in the last three months. Leaded or lead free processes?
