Guide to Assembly of Marki Microwave Surface Mount Components

The purpose of this document is to provide guidance to board designers, layout engineers, contract manufacturers, and others responsible for the fabrication and assembly of systems using Marki Microwave surface mount (SMT) components. Marki Microwave is committed to creating components that enable the highest performance systems in the world. This entails using unique packaging that allows for high performance components while remaining compatible with standard surface mount reflow processes. Appropriate care must be taken when designing and qualifying the assembly process to ensure that parts are not damaged.

This paper is intended as a basis for understanding the processes necessary to assemble Marki components into systems. It is highly recommended that customers qualify their assembly process well before the volume production stage to ensure that yields are satisfactory. Most assembly problems do not appear as a 100% failure rate, but instead as lower than required production yield.
