Now Available: Amendments for J-STD-001F and IPC-A-610F
In order to keep up with industry demand, IPC has released amendments for J-STD-001F, Requirements for Soldered Electrical and Electronic Assemblies, and IPC-A-610F, Acceptability of Electronic Assemblies. For each standard, IPC-A-610F Amendment 1 and IPC J-STD-001F Amendment 1 represents a critical shift to deliver necessary updates to these already robust standards.
With topics ranging from vertical hole fill to BGA voiding, these amendments include updates that:
Reintroduce the Space Shuttle symbol to show where there are different criteria in the J-STD-001FS, Space Applications Electronic Hardware Addendum to IPC J-STD-001F, Requirements for Soldered Electrical and Electronic Assemblies
Revise the Class 2 requirements for vertical solder fill on plated through holes with less than 14 leads to include requirements when there is a connected internal thermal plane
Eliminate requirements for BGA voiding for BGA components with noncollapsing balls
Solder joint encapsulant adhesives have been successfully used to enhance the strength of solder joints and improve thermal cycling as well as drop performance in finished products. The use of solder joint encapsulant adhesives can eliminate the need for underfill materials and the underfill process altogether, thus simplifying rework, which results in a lower cost of ownership.
(...) In this paper, we are going to discuss the details and future of solder joint encapsulant adhesives.
