MPPE/SEBS Composites with Low Dielectric Loss for High-Frequency Copper Clad Laminates Applications

Copper clad laminates (CCLs) with low dissipation factor (Df) are urgently needed in the fields of high-frequency communications devices. A novel resin matrix of modified poly (2,6-dimethyl-1,4- phenylene ether) (MPPE) and styrene-ethylene/butylene-styrene (SEBS) was employed in the fabrication of high-frequency copper clad laminates (CCLs). The composites were reinforced by E-glass fabrics, which were modified with phenyltriethoxysilane (PhTES). The composite laminates obtained exhibited impressive dielectric loss of 0.0027 at 10 GHz when the weight ratio of MPPE to SEBS was 5:1.

Reliability and Failure Mechanisms of Laminate Substrates in a Pb-free World

This presentation surveys the most significant via and via-related laminate failure mechanisms from past to present using data from current induced thermal cycling (CITC) testing, failure analysis, and other sources. The relative life and failure modes of thru vias, buried vias, and microvias (stacked vs. non-stacked) are compared, along with the affect of structure, materials, and peak temperatures on the above. The origin of via-induced laminate failures such as "eyebrow cracks" and Pb free related internal delamination is also explored.

An Experimental Investigation of Fracture Toughness and Volume Resistivity of Symmetric Laminated Epoxy/ Glass Fiber/CNT multiscale composites

In this work an attempt is made to improve the fracture toughness and electrical conductivity of epoxy/glass fiber based laminates by the inclusion of carbon nanotube (CNT) fillers. The fiber orientation of the epoxy/ glass fiber (GF) fabric laminates was optimized based on estimation of mechanical properties. The carboxylic acid functionalized CNTs were incorporated into epoxy matrix by ultra-sonication method. The nano filled epoxy resin was used to prepare laminates with 30/45 GF fabric orientation. The CNT content was varied and its effect on the tensile properties was determined. The fracture toughness of multiphase composites was estimated using single edge notch bend (SENB) test. The presence of CNTs improved the fracture toughness by a crack bridging mechanism. The volume resistivity of multiphase composites was found to be superior to the conventional epoxy/CNT composite. The presence of glass fabric reduces the number of inter-tube contacts contributing to the reduction in volume resistivity.

Everything You Ever Wanted to Know About Laminates... but Were Afraid to Ask

It has been over 25 years since the earliest edition of "Everything You Ever Wanted to Know About Laminates...but Were Afraid to Ask" was pounded out on an old TRaSh-80 Computer. It has undergone periodic review and editing, including adaption for use on our website. When I entered the industry Al Gore had not yet invented the internet. Before I "retired" in 2004, we did another minor revision, but it was largely cosmetic, removing most references to the old military specification and introducing IPC-4101, the "new" specification for laminate and prepreg materials.

Making Sense of Laminate Dielectric Properties

System operating speeds continue to increase as a function of the consumer demand for such technologies as faster Internet connectivity, video on demand, and mobile communications technology. As a result, new high performance PCB substrates have emerged to address signal integrity issues at higher operating frequencies. These are commonly called low Dk and/or low loss (Df) materials. The published "typical" values found on a product data sheet provide limited information, usually a single construction and resin content, and are derived from a wide range of test methods and test sample configurations. A printed circuit board designer or front end application engineer must be aware that making a design decision based on the limited information found on a product data sheet can lead to errors which can delay a product launch or increase the assembled PCB cost. The purpose of this paper is to highlight critical selection factors that go beyond a typical product data sheet and explain how these factors must be considered when selecting materials for high speed applications

JUKI and USB 2 Floppy Disk emulator -- Can anybody recomend exact model number of USB to floppy disk emulator, which works for sure on JUKI KE7xx series PnP machines? I have bought this one : https://www.gotekemulator.com/P_view.asp?pid=54 and have KE760 machine, but it doesnt work. We tried to create small partition 2Gb , formatted to FAT16, still no luck. Seems there is alot firmware options, as back those days there were not many standards implemented yet, and alot HW incompatibilty could be observed ... this manufacturer has about 50different versions https://floppyusbemulator.com/shop?orderby=price-desc&product_cat=n-drive-industrial&count=60

Ultrasonic immersive flux removing safe for LEDs -- Can anybody recomend a LED-safe flux removing/cleaning liquid, which can be used in ultrasonic cleaner in immersive application? After using one product I have been told, that none of the top suppliers of chemicals have this kind of liquid (subject to individual tests, which I am trying to avoid, as corrosion on LED inner leaded frame/ reflector can be noticed in distance of 1year.....I want to use certified material, which passed such long term tests. Any ideas?
