Charley, I have worked on QP242's for 1 and 1/2 years. It is a very reliable machine but like all machines, PM's are very important. When I first got to NOKIA I wasn't familiar with the QP's. Mostly IP3's, IP2's. We are placing 16 mil pitch parts

Currently, lots of OEM or CM's have moved to China already. Solectron, Flextronic, Motorola, Nokia & Ericsson. Sooner or later, SMT assembly equipment will move their manufacturing plan to China.

Hi Chics, It all depends on where you are in the world - in Europe robots were used back end (Ericsson), and usually Fujis front end (Motorola, Nokia, Ericsson). In China you're obviously not going to need the Robots.... Cheers, Rob.

There are multiple solder alloy options and we have tested many of them in a consortium project. There also are very specific challenges associated with testing using the -40/150 C profile. This is way too complicated to discuss in a chat room. Se

Here at M/A-Com we use lead free solder pastes for two purposes, environment and prevention of secondary reflow in subsequent processes. The UK engineering journals all report the trends towards lead free alloys, especially in the telecommunications

I think forgot one most important thing. SMT is not all. In China, after the SMT process, QC, QA, casting, packing etc. It need lots of labors. I really one worker can handle 4 lines. Nokia still have two bid factory in China, Motorola has two also.
