This chapter will review the current and developing standards, which affect lead-free soldering. Developments in standards for lead-free soldering are not complete and are progressing with new discoveries and developments. The majority of the chapter will cover IPC standards with reference to other standards, which are considered relevant and 由ipc产品保证委员会（7-30） 维修分委员会（7-34）开发， 由ipc tgasia 7-34cn技术组翻译。 鼓励本标准的使用者参加未来修订版的开发。 联系方式： ipc 中国 取代： ipc-7711b/7721b附修订本1和 修订本2，2007年11月 修订本1，2013年2月 修订本2，2014年3月 ipc-7711a/7721a，2003年 In the second method the IPC 7711 method 5.8.1.2. was used to "bump" the parts. Once bumped, the parts were inserted in to the stencil on the board (Figure 3). The matrix of the experiment is given in Table 1 below. Table 1: Number of QFN's reworked once or twice for vibration, drop, and thermal cycle testing using a "traditional" hot He is Certified IPC Master Trainer for IPC-A-600, IPC-6012, IPC-A-610, IPC/WHMA-A-620, IPC-J-STD-001, IPC 7711/21 and IPC-J-STD-001 (Space).

This test is carried out under high humidity and under heat stress in climatic chambers. IPC Standards: A Guide to Standards for PCB Manufacturing IPC, stands for Association Connecting Electronics Industries, and it is the abbreviation of its initial name "Institute of Printed Circuits" in the fall of 1957. IPC is the only trade association that brings together all of the IPC 3000 Lakeside Drive, Suite 309S Bannockburn, IL 60015-1249 Phone ( 847) 615-7100 Fax (847) 615-7105 Supersedes: J-STD-001E - April 2010 J-STD-001D - February 2005 J-STD-001C - March 2000 J-STD-001B - October 1996 J-STD-001A - April 1992 If a conflict occurs between the English and translated versions of this document, the English IPC-HDBK-830 IPC-7095C IPC-7711/21B IPC-620B J-STD-002C J-STD-003B. Is it OK!! This standard will help you to solve problems? No if applied singularly !! Process Engineer Operator Operator Operator Quality Inspector The electronic assembly works when all use and are ready to apply The PCB was conformal coated with a non-corrosive, one-part, fast moisture curing, RTV silicone elastomer (Dow Corning 3-1965). This coating offers good dielectric properties over a wide frequency range and resists high humidity and other harsh environments. The silicone can be applied by spraying, dipping, brushing, and flow coating.
