Using Flux-Coated Solder Preforms to Repeatably Achieve Low Voiding in Power ICs: An Automotive Case Study

For an automotive transmission control unit (TCU) platform, the bottom ground pad of a high power low-profile quad flat package (LQFP) component soldered to the thermal pad of the PCB had a .. read more

Miniaturization with Help of Reduced Component to Component Spacing

Miniaturization and the integration of a growing number of functions in portable electronic devices require an extremely high packaging density for the active and passive components. There are .. read more

Solder Paste Stencil Design for Optimal QFN Yield and Reliability

The use of bottom terminated components (BTC) has become widespread,specifically the use of Quad Flat No-lead (QFN) packages. The small outline and low height of this package type,improved elec .. read more

Quantifying Stencil Aperture Wall Quality
