Selection and rcementepla of Material PCL-370HR

September 2nd, 2015 | Posted by admin in Guidelines | PCB Material - (Comments Off on Selection and rcementepla of Material PCL-370HR)

370HR is a high performance 175 glass transition temperature(Tg) FR-4 system for multilayer Printed Wiring Board (PCB) applications where maximum thermal performance and reliability are required. 370HR laminate and prepreg products are manufactured with a unique high performance multifunctional epoxy resin, reinforced with electrical grade (E-glass) glass fabric. We did receive many RFQs with specified …

PCB CTI, TG, TD, TCE, DBV, WA explaination

October 11th, 2013 | Posted by admin in PCB Material - (Comments Off on PCB CTI, TG, TD, TCE, DBV, WA explaination)

CTI Stands for Comparative Tracking Index. It  is expressed as that voltage which causes tracking after 50 drops of 0.1 percent ammonium chloride solution have fallen on the material. The results of testing the nominal 3 mm thickness are considered representative of the material’s performance in any thickness. It indicates the highest usable voltage for …

FR1-FR3, CEM1-CEM3,FR4, Aluminum Flex CCL introductions

October 6th, 2013 | Posted by admin in PCB Material - (Comments Off on FR1-FR3, CEM1-CEM3,FR4, Aluminum Flex CCL introductions)

FR1-FR4 FR1 is basically the same as FR2. FR1 has a higher TG of 130oC instead of 105oC for FR2. Some laminate manufacturers who produce FR1 may not produce FR2 since the cost and usage are similar and it is not cost effective for having both. FR3 is also basically FR2. But instead of phenolic …

Summary of all available PCB CCL

October 3rd, 2013 | Posted by admin in Guidelines | PCB Material - (Comments Off on Summary of all available PCB CCL)

Various requirements for printed circuit boards make the use of different circuit board substrates necessary. Whereas for many standard applications the classical FR4 material is sufficient, possibly in high Tg version (for improved thermo-mechanical properties), for other areas (such as high frequencies) alternate materials are absolutely required. The following information is intended as a abstract …
