Cecil, the board is a component.

maximum number of reflow cycles for rigid PCB?

Just askin but why would someone even want to subject an assembly to even 6 reflow cycles? As far as how many cycles that an assembly can be subjected to, wouldn't that be determined my your components?

A Life Prediction Model of Multilayered PTH Based on Fatigue Mechanism

Technical Library | 2019-12-26 19:13:52.0

Plated through hole (PTH) plays a critical role in printed circuit board (PCB) reliability. Thermal fatigue deformation of the PTH material is regarded as the primary factor affecting the lifetime of electrical devices. Numerous research efforts have focused on the failure mechanism model of PTH. However, most of the existing models were based on the one-dimensional structure hypothesis without taking the multilayered structure and external pad into consideration.In this paper, the constitutive relation of multilayered PTH is developed to establish the stress equation, and finite element analysis (FEA) is performed to locate the maximum stress and simulate the influence of the material properties. Finally, thermal cycle tests are conducted to verify the accuracy of the life prediction results. This model could be used in fatigue failure portable diagnosis and for life prediction of multilayered PCB.

Does Thermal Cycling Impact the Electrical Reliability of a No-Clean Solder Paste Flux Residue

Technical Library | 2018-08-29 21:17:53.0

No-clean solder pastes are widely used in a number of applications that are exposed to wide variations in temperature during the life of the assembled electronics device. Some have observed that cracks can and do form in flux residue and have postulated that this is the result of or exacerbated by temperature cycling. Furthermore, the potential exists for the flux residue to soften or liquefy at elevated temperatures, and even flow if orientated parallel to gravity. In situations such as in automotive electronics, where significant temperature cycling is a reality and high reliability is a must, concern sometimes exists that the cracking and possible softening or liquefying of the residue may have a deleterious effect on the electrical reliability of the flux residue. This paper will attempt to address this concern.

The Effect of Vacuum Reflow Processing On Solder Joint Voiding And Thermal Fatigue Reliability

Heller 公司 | http://hellerindustries.com.cn/Vacuum-Void-Reduction-Reflow.pdf

joint failures from the TC1 0/100 °C thermal cycling test are shown in the optical photomicrographs in Figure 12. The large solder voids reduce the effective attachment area through which the crack propagates, thereby reducing the number of cycles to
