SIR Test Method for Developing Evidence for the Production Assembly
SIR Test Method for Developing Evidence for the Production Assembly
The purpose of this paper is research on the development of temperature-humidity-bias instrumentation and test board designs for product acceptance. This paper reported research on both test boards and instrumentation for use at the assembly site. The instrument and test board combinations are tools to develop objective evidence.

Reduction of Condensate Residues in the Reflow Process
Reduction of Condensate Residues in the Reflow Process
Increased electronics manufacturing results in an increased amount of condensate residue. The problem is not only to meet the increased cleaning requirements with increasing production, it is much more the absence of knowledge about the condensate residue formation process and how this residue can be minimized and inhibited in its formation.
