I am looking for an IPC spec for intentional PCB warp

Electronics Forum | Mon Dec 22 16:20:03 EST 2014 | warwolf

Basically the contract comes first, then the design drawings then IPC. if your costumer is asking you to bend the PCB then it becomes apart of the design drawings. as for looking for a cover, get it in writing that that's what they want you to do. I

Standard of PCB Bow and Twist in Incoming Inspecion

Electronics Forum | Thu Feb 27 12:27:10 EST 2003 | stevel

Hi all, We got some bare pwb in our incoming inspecion looked really wrapped. The maximum twist of the pwb we messured is 0.056inch by following the method in IPC-TM-650 2.4.22 C. (The diagonal size of our pwb is 7.5inch) According to the IPC standa

Ready to Start Measuring PCB Warpage during Reflow? Why and How to Use the New IPC-9641 Standard

Technical Library | 2014-08-19 15:39:13.0

Understanding warpage of package attach locations on PCBs under reflow temperature conditions is critical in surface mount technology. A new industry standard, IPC 9641, addresses this topic directly for the first time as an international standard.This paper begins by summarizing the sections of the IPC 9641 standard, including, measurement equipment selection, test setup and methodology, and accuracy verification. The paper goes further to discuss practical implementation of the IPC 9641 standards. Key advantages and disadvantages between available warpage measurement methods are highlighted. Choosing the correct measurement technique depends on requirements for warpage resolution, data density, measurement volume, and data correlation. From industry experience, best practice recommendations are made on warpage management of PCB land areas, covering how to setup, run, analyze, and report on local area PCB warpage.The release of IPC 9641 shows that flatness over temperature of the package land area on the PCB is critical to the SMT industry. Furthermore, compatibility of shapes between attaching surfaces in SMT, like a package and PCB, will be critical to product yield and quality in years to come.

Design Rules For Selective Soldering Assemblies

Technical Library | 2018-02-14 22:58:54.0

This document describes general guidelines and attention points for PCB design regarding selective soldering. The guidelines can be applied for Select Wave and/or Multi Wave soldering process in both leaded and leadfree alloy. When a PCB is designed according to these guidelines, a stable and solid solder-process can be guaranteed.
