JOINT IPC/JEDEC Standard Moisture/Reflow Sensitivity Classification for Non-hermetic Surface Mount Devices (SMDs) This legacy document is a comprehensive users’ guide for silicon rectifier diode applications. This publication provides an overview of solder void types, outlines current metrologies and test methods used for pre-SMPT solder void characterization and potential limitations, and prescribes sampling strategy for data collection, and tolerance guidelines for corrective measures.

MMC Electrical Interface, its environment and handling.The purpose of this standard is the definition of the e It also provides design guidelines and defines a tool box of macro functions and algorithms intended to reduce design-in overhead. MMC Electrical Interface, its environment, and handling.This document provides a comprehensive definition of the e Status: Rescinded, May 2000ĮMBEDDED MULTI-MEDIA CARD (e MOISTURE-INDUCED STRESS SENSITIVITY FOR PLASTIC SURFACE MOUNT DEVICES - SUPERSEDED BY J-STD-020A, April 1999. This test method is to measure the deviation from uniform flatness of an integrated circuit package body for the range of thermal conditions experienced during the surface-mount soldering operation. Package Warpage Measurement of Surface-Mount Integrated Circuits at Elevated Temperature The heat is conducted through the leads into the device package from solder heat at the reverse side of the board. This test method is used to determine whether solid state devices can withstand the effect of the temperature shock to which they will be subjected during soldering of their leads in a solderwave process and/or solder fountain (rework/replacement) process. RESISTANCE TO SOLDER SHOCK FOR THROUGH-HOLE MOUNTED DEVICES Status: Reaffirmed February 2023 This Guideline specifically focuses on the “Assembly Process Classification” subsection of the Part Model.įor more information visit the main JEP30 webpage. It forms part of the Part Model XML Schema, which covers the parental structure for the electrical, physical, thermal, assembly process classification data along with materials and substances that may be present in the supplied product or subproducts. This standard applies to all forms of electronic parts. This standard establishes the requirements for exchanging part data between part manufacturers and their customers for electrical and electronic products.
