High Tg laminates

Electronics Forum | Tue Nov 16 18:02:29 EST 1999 | John Holland

What are the main advantages of moving from a 140 degree C FR4 laminate to a higher Tg laminate 180 degree C ?. Would the higher Tg laminate be less susceptable to bow and twist ?. John Holland

so, why are your laminates warped? What needs to be done to correct that issue?

Transparent Laminate

We are aware of no transparent laminates. Most are roughly translucent, with a milky white color. Some laminated are quite thin and could serve your purpose. As an alternative, could you etch foil [that's readily available] and the attach the etch

bwjm: Delamination can be attributed to several factors: * Entrapped moisture, processing solutions, and what not that expands when heated to normal soldering temperature * Excessive soldering temperature * Excessive laminating temperature * Def

Dr. Lee, Given the higher reflow temperatures for Pb-Free assembly, will common FR4 laminate materials be adequate, or do you believe that higher glass content boards will be required for mainstream Pb-free assembly? As a corollary question - if man

Hello, Our PWB supplier has requested that a change in the laminate material to reduce the incidence of pad lifting. The standard laminate materials (Polyclad PCL-FR-226 with a glass transition temperature of 135 C) have greater z-axis thermal expan

RoHS Board Delamination

SWAG - I also forgot to mention a few things. Our delmaination was always between the large copper plane and the laminate. It is a multi-layered board, so even when the delamination appeared around components (through visual inspection), cross-sect

PCB laminate dielectric absorption

Electronics Forum | Wed Dec 13 13:42:57 EST 2000 | Mike Ihm

The dielectic absorption characteristic of printed circuit board materials is usually not listed on the manufacturers spec. sheets. Can anyone point me in a direction to help determine which laminate materials might exhibit better dielectric absorpt
