IPC TM-650 2.3.19-1994 预浸料的挥发份含量 修订版C 1994年12月

This document covers guidelines for selecting electrically conductive adhesives for use in assembly of components to printed circuit boards (PCB) or similar wiring interconnect systems. The focus is on the use of adhesives as solder alternatives. The process discussion attempts to stay within the bounds of the existing solder assembly infrastructure as much as possible. Both major types of adhesives, isotropic (conducting equally in all directions) and anisotropic (unidirectional conductivity), are covered. The two major divisions of polymer adhesives, thermosets and thermoplastics, are described.

This standard provides the principles and details for declarations necessary between members of a supply chain. Although this standard contains only generic information regarding trading partners, when combined with a specific sectional standard, the entire document set is used to define and maintain the declaration type information. The requirements pertain to both hard copy and electronic data descriptions. This standard provides for the creation of a record that will serve as a commitment between trading partners and may be used to establish due diligence in any dispute in third-party litigation.

IPC TM-650 2.3.18-1986 预浸材料凝胶时间 修订版A 1986年4月

This Standard covers dimensioning and tolerancing of electronic packaging as it relates to printed boards and the assembly of printed boards. The concepts defined in this Standard are derived from ASME Y14.5” 1994. Printed boards have such wide applications that there may be times where this standard does not address a specific case. In those cases, the user is referred to ASME Y14.5M 1994 for use of additional dimensioning and tolerancing concepts.
