Thanks for the tips... found out the ex-employee guy, had pre-bake conditioning put into the process flow, as this pcb is made of polymide material, that is reputed to have historical patterns in thermal sensitivity. To avoid "thermal damaging" the

Hi, Can anyone help explain the benefits/disadvantages of bareboard pcb baking, as part of the pre-heat conditioning, before the bareboard pcb use in SMT production run? The pcb board is 200mm x 240mm panelized pcb board, and has 28 smaller pcb boa

The conversion to higher temperature "Lead Free" assembly reflow conditions has created an increased awareness that entrapped or absorbed moisture is a frequent root cause of thermally induced delamination at assembly reflow. There are two connected failure modes from entrapped moisture; incomplete resin cross-linking resulting in premature resin decomposition and also severe Z axis expansion from "explosive vaporization of the entrapped moisture at elevated temperatures at assembly reflow". Ultimately, both result in delamination failure. Other papers have shown the negative effects of entrapped moisture before lamination including delamination, red color, reduced thermal reliability and increased high speed signal loss. In this paper, various materials were tested for moisture sensitivity during lamination. Tests were performed at varying lamination conditions including a pre-vacuum step and "kiss" step. Pressure and cure temperature parameters were evaluated for minimizing or eliminating the effect of trapped moisture. Also included are the results of inner layer moisture removal baking conditions and their effect on peel strength and thermal reliability.
With the development of miniaturization of assembly components, the layout area and pattern design area of PCBs have also been continuously reduced, and PCB manufacturers are constantly updating the production process to conform to the development tr
