What is DD IEC/PAS 62326-7-1 – Printed wiring boards about?
DD IEC/PAS 62326-7-1 is a part of an international standard that covers the performance guidance for printed wiring boards.
DD IEC/PAS 62326-7-1 provides the requirements for the single- and double-sided flexible printed wiring boards (hereinafter designated as "flexible printed board" or FPC).
DD IEC/PAS 62326-7-1 specifies the technicalities such as related terms and definitions, test methods, performance levels, base materials, visual inspection, dimensional inspections, electrical performance test, mechanical performance test, environmental performance, chemical resistance, flame resistance, etc., for single- and double-sided flexible printed wiring boards.
Who is DD IEC/PAS 62326-7-1 – Printed wiring boards?
DD IEC/PAS 62326-7-1 on printed wiring boards are useful for:
- Manufacturers of electronic components and interconnecting structures
- Manufacturers of printed circuit boards (PCBs)
- Manufacturers of printed wiring boards
- Manufacturers and suppliers of laminate sheets
- Quality control and testing personnel
- Regulatory authorities
Why should you use DD IEC/PAS 62326-7-1 – Printed wiring boards?
Flexible printed wiring boards also called flexible printed circuits (FPC), are a single- or double-sided FPC prepared by lamination of a film of polyester or polyimide with copper foil(s) on one or both sides of a printed board. It includes the type with no adhesive layer and with a conductor pattern formed by the subtractive method (etching of the copper foil), or possibly by the build-up method.
DD IEC/PAS 62326-7-1 covers the technicalities for the flexible printed wiring boards such as requirements for base materials, and classification of FPC based on their performance level. This helps the users to select the relevant level of the board for a specific application. It also guides for choosing a different level for a specific section of the board as per the relevant specification of another part of the board.
DD IEC/PAS 62326-7-1 lays out the various test procedures for verifying the electrical properties, mechanical properties, chemical resistance as well as environmental performance of the flexible printed wiring boards. It also illustrates specifications for visual inspections and dimensional inspections of the printed wiring boards.
DD IEC/PAS 62326-7-1 contributes to the designing and manufacturing of high-quality, reliable, efficient, and durable printing wiring boards. It helps in preparing an agreement between user and supplier, as per the limit samples show the required criteria to make technical judgments.
