I am trying to teach a class and the question came up about loss of metalization of the Earth pad on a chip filter. This pad is on the side of the component. I can not find a IPC call out for this type of side termination other than 3 or 5 sided 9.1.

Over the past years there has been consistent growth in the use of electroless nickel / immersion gold (ENIG) as a final finish. The finish is now frequently being used for PBGA, CSP, QFP and COB and more recently gathered considerable interest as a low cost under-bump metallization for flip chip bumping application. One of the largest users for this finish has been the telecommunication industry, were millions of square meters of PCBs with ENIG have been successfully used. The nickel layer offers advantages such as multiple soldering cycles and hand reworks without copper dissolution being a factor. The nickel also acts as a reinforcement to improve through-hole and blind micro via thermal integrity. In addition the nickel layer offers advantages such as co-planarity, Al-wire bondability and the use as contact surface for keypads or contact switching. Especially those pads, which are not covered by solder need a protective coating in corrosive environment – such as high humidity or pollutant gas.

This paper deals with the thermal effects of joule heating in a high interconnect density, thin core, buildup, organic flip chip substrate. The 440 μm thick substrate consists of a 135 μm thick core with via density of about 200 μm. The typical feature sizes in the substrate are 50 micron diameter vias is the core/buildup layers and 12 micron thick metal planes. An experimental test vehicle is powered with current and the temperature rise was measured. A numerical model was used to simulate the temperature rise in the TV.
BGA integrated circuits and chip scale packages, CSPs where the solder connections are not visible. This has arisen as a result of the need for greater numbers of interconnections to integrated circuit packages and as a general result of increasing c
