Manish, I've seen similar phenomenon when processing CSPs on our cards. In our case, we were placing the components over the opening to in-pad blind vias. Due to poor drilling and plating processes by our board suppliers, volatiles were outgassing

Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a huge chance with Specnor. If the motor doesn't come in or if it doesn't work, then I'm dead. They told me I'd have the motor next day. They kept trying to sell me

Everything went smoothly. I had the motor in less than one day. And I saved $690 from Electrovert's $1170 price (slightly different model but it works great!). | Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a

So my salesman says to me that we could return our unneeded Al frames from our MPM printer to Alphametals in CA for credit to be applied toward a future sale. Sonded good. So I boxed up all the damn frames (44) and shipped them off to Goofyland. Now

| I'm reviewing my board fab spec. It calls for a minimum SnPb thickness of 50 microinches on HASL PWB's. I've looked at other specs that call out anything from 30 to 80 microinches, and others that just say the copper pad must be covered and solde

| We had some failures on an IC package that the manufacturer has put down to moisture inside the package, leading to popcorning. | This seems a bit odd, the package is a PLCC 84 which is quite thick. I have only seen this problem on thin packages. |
