Polyphenylene Ether Macromonomers. XI. Use in Non-Epoxy Printed Wiring Boards

The continuous progression toward portable,high frequency microelectronic systems has placed high demands on material performance,notably low dielectric constants (Dk),low loss tangent (Df),low .. read more

Impact of Dust on Printed Circuit Assembly Reliability

Atmospheric dust consists of solids suspended in air. Dust is well known for its complex nature. It normally includes inorganic mineral materials,water soluble salts,organic materials,and a sma .. read more

HDPUG Pb-Free Board Materials Reliability Project 2 Moisture Sensitivity and Its Effect on Delamination

As part of High Density Packaging Users Group (HDPUG) Pb-Free Board Materials Reliability Project 2,the moisture sensitivity of various lead-free laminates and the effect of moisture uptake on .. read more

Moisture Measurements in PCBs and Impact of Design on Desorption Behaviour

High levels of residual moisture in PCBs are problematic and can result in delamination during soldering and rework. Moisture accumulates during storage and industry practice recommends specifi .. read more

Toughened Laminates for Printed Circuit Boards: Correlation of Drillability to Material Properties

With the miniaturization of electronic devices1,the need for more versatile materials to make these devices increases. Coupled with the gradual removal of lead-based solders2,thermal stability .. read more

Water Vapor Uptake and Release in Printed Boards

Excessive moisture entrapped/absorbed within printed board laminates can expand during soldering operations,causing delamination or other damage. While moisture absorption data is available for .. read more

Polyphenylene Ether Macromonomers. Iii. Enhancement of Dielectric Materials

Two major trends in printed wiring boards electronics are applications that require higher operating frequency,often in the radio frequency range (GHz),and the use of lead free solder assembly. .. read more

RoHS and Green Compliance in IC Packaging

In this report,BGA packages with conventional and green material combination were selected as test vehicles for the investigation of MSL/temperature rating at the packaging level. The IC packag .. read more

Thermoplastic Injection Molding: New Packages and 3D Circuits

Thermoset epoxies,discovered nearly 80 years ago,remain the workhorse materials for electronic packaging and printed circuit boards,but this may change with increasing technical,economic and re .. read more
