How long and at what temperature to you bake through-hole boards for moisture? I am getting blow holes after the wave solder. Everything points to the drilling of the board, but I need to prove that it is not moisture.

Are there any other manual reballing systems aside from the one made by Hepco that use a vacuum method for ball placement?

Our company do electronic packaging for space applications. One of the problems we face during our design is whether or not to stake/bond the surface mount components to the board to survive the vibration qualification environment. If we do staking

In the Chapter 3 on "Thermal & Mechanical Stress," Harry Charles mentions a "homologous point" in 3.5. We are unfamiliar with this term. What is this point? What are the implications of solders in operating environments below their homologous poin

The homologous point is the temperature midway betweeen the melting temperature (of the solder) and absolute zero. Below this point the solders are harder, stronger, and more resistant to fatigue. As solders are exposed to higher temperatures above

Does anyone know of any interchangeable stencil frame systems? We use Alpha's Metals Smart Frame system,but it is heavy and cumbersome. Also, are there any quality issues that prove the interchangeable system is not as repeatable as the permanently
