| Do anyone have any experience on assembling high frequency product, 1.8GHz or 2.4GHz. | | In our production line, we manufacture 1.8GHz product with using no clean paste (RMA type) for reflow and no clean wire for rework. In our functinal test,eit

| Has there anyone bold enough to try this in their shops? My cubemate just got through telling me that at his last shop, they had bare copper boards (no HASL, no OSP, no nothing), with minimal solderability problems. | yes, 8 years ago I developed

| Now don't everyone jump on this at once, but it seems time for me to send out copies of my not even close to being dated copy of an article about HASL. Though it was published in 1992, in Printed Circuit Fabrication Magazine, and it got rave review

| A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for po
