Abstract: Industry standards and practices today do not adequately address issues associated with the use of process sensitive components. The consequences may be significant for complex board assemblies in high reliability or mission critical applications where hotter and longer assembly processes are not uncommon due the nature of these products as opposed to their consumer product counterparts. Under these conditions, process sensitive components may fail when exposed to elevated process temperatures or chemicals outside their qualified parameters. Some failures may occur at time zero, but also there may be a reduction in the long term reliability of the components. Depending on the lifetime reliability requirements of the system level product, product owners risk quality and reliability impacts caused by these time dependent failures. Additional awareness of the concerns and an understanding of best practices could aide the industry in managing temperature sensitive components.

To address some of these shortcomings, the High Density Packaging (HDP) User Group consortium has undertaken the publication of a Process Sensitive Components Industry Guideline Document. This Guideline includes information on component construction and temperature induced failure mechanisms to help contract manufacturers (CMs) and original equipment manufacturers (OEMs) optimize their processes associated with process sensitive components. The CMs will learn which components can be expected to have limitations and benefit from the documentation of best practices to know to adjust their processes accordingly. The OEMs will learn how they will need to develop business processes to manage component information obtained from their suppliers and supervise the assembly process development at their CMs. In addition, this Guideline document defines proper interpretation and usage of J-STD-020 and J-STD-075 to promote more widespread understanding and use of these industry standards.

This paper will provide highlights of the content of the PSC Guideline document to increase industry awareness and encourage education regarding process sensitive components throughout the supply chain.
