This handbook has been developed to aid Printed Circuit Board manufacturers and users of Printed Circuit Boards in completing Material Declarations that follow the format and guidance of the Joint Industry Material Composition Declaration Guide for Electronic Products. Purpose This...
Overview The continuing trend to finer features on PCBs increased the negative effect of particles on board yields. Cleanrooms provide a logical way to reduce the effect of particles, and are more critical as finer lines are required. Cleanrooms have been used since at least the 1970s...
This document describes time domain reflectometry (TDR) methods for measuring and calculating the characteristic impedance, Z(0), of a transmission line on a printed circuit board (PCB). In TDR, a signal, usually a step pulse, is injected onto a transmission line and the Z(0) of the...
This part of IEC 60749 provides a test method that is intended to evaluate and compare drop performance of surface mount electronic components for handheld electronic product applications in an accelerated test environment, where excessive flexure of a circuit board causes product failure....
This part of ISO 11452 specifies harness excitation test methods and procedures for determining the immunity of electronic components of passenger cars and commercial vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The bulk current injection...
This document describes various materials that can be used for the fabrication of high density interconnection (HDI) and microvias. It provides information on general classifications and associated characteristics of HDI materials. The document shall be used as a qualification and conformance...
