Folks, I think we are getting closer to being very happy with DEK stencil printers of the 265 GSX variety. However, problems continue arising concering fine pitch autoflex tooling pin breakage. We are told by the British engineering establishment,

Over the past few years, pad cratering has become a vexing problem in lead-free assemblies, largely attributed to problems with the resin used to make a printed board. To help industry eliminate the defect and, at the same time, cut costs, IPC — Association Connecting Electronics Industries® has released IPC-9708, Test Methods for Characterization of PCB Pad Cratering.

Nordson DAGE, a division of Nordson Corporation (NASDAQ: NDSN) have adopted the company’s hot pin pull test method for checking the integrity of solder ball attach on packages and PCBs in accordance with the industry standard IPC9708. This particular standard provides guidelines for bond testing to identify potential pad craters.

Pad cratering has become more prevalent with the switch to lead free solders and lead free compatible laminates. This mainly is due to the use of higher reflow temperature, stiffer Pb-free solder alloys, and the more brittle Pb-free compatible laminates. However, pad cratering is difficult to detect by monitoring electric resistance since pad cratering initiates before an electrical failure occurs. Several methods have been developed to evaluate laminate materials' resistance to pad cratering. Pad-solder level tests include ball shear, ball pull and pin pull. The detailed methods for ball shear, ball pull, and pin pull testing are documented in an industry standard IPC-9708. Bansal, et al. proposed to use acoustic emission (AE) sensors to detect pad cratering during four-point bend test. Currently there is an industry-working group working on test guidelines for acoustic emission measurement during mechanical testing.

Pad cratering is an important failure mode besides crack of solder joint as it’ll pass the regular test but have impact on the long term reliability of the product. A new pin pull test method with solder ball attached and positioning the test board at an angle of 30º is employed to study the strength of pad cratering. This new method clearly reveals the failure mechanism. And a proper way to interpret the finite element analysis (FEA) result is discussed. Impact of pad dimension, width and angle of copper trace on the strength is included. Some findings not included in previous research could help to guide the design for better performance
