Weak joint strength and black residue

Electronics Forum | Fri Jun 08 17:22:51 EDT 2007 | naynayno

We have been producing an IMS assembly with SMT dpak's for some time. However, we recently encountered a new problem by chance - the parts can be flicked off with a finger nail. I state by chance because the solder joints are wetted and shiny with

Challenges on ENEPIG Finished PCBs: Gold Ball Bonding and Pad Metal Lift

Technical Library | 2017-09-07 13:56:11.0

As a surface finish for PCBs, Electroless Nickel/Electroless Palladium/Immersion Gold (ENEPIG) was selected over Electroless Nickel/Immersion Gold (ENIG) for CMOS image sensor applications with both surface mount technology (SMT) and gold ball bonding processes in mind based on the research available on-line. Challenges in the wire bonding process on ENEPIG with regards to bondability and other plating related issues are summarized.

Board Design and Assembly Process Evaluation for 0201 Components on PCBs

Technical Library | 2023-05-02 19:06:43.0

As 0402 has become a common package for printed circuit board (PCB) assembly, research and development on mounting 0201 components is emerging as an important topic in the field of surface mount technology for PWB miniaturization. In this study, a test vehicle for 0201 packages was designed to investigate board design and assembly issues. Design of Experiment (DOE) was utilized, using the test vehicle, to explore the influence of key parameters in pad design, printing, pick-andplace, and reflow on the assembly process. These key parameters include printing parameters, mounting height or placement pressure, reflow ramping rate, soak time and peak temperature. The pad designs consist of rectangular pad shape, round pad shape and home-based pad shape. For each pad design, several different aperture openings on the stencil were included. The performance parameters from this experiment include solder paste height, solder paste volume and the number of post-reflow defects. By analyzing the DOE results, optimized pad designs and assembly process parameters were determined.
