TMM3 High Frequency Printed Circuit Board 15mil 30mil 60mil DK3.27 RF PCB With
Immersion Gold
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
General
Description
It has the dielectric constant of 3.27 and dissipation factor of
0.002.
TMM3
has an exceptionally low thermal coefficient of dielectric constant. Its
isotropic coefficients of thermal expansion is very closely matched to copper
which results in production of high reliability plated through holes, and low
etch shrinkage values. Furthermore, the thermal conductivity of TMM3 is
approximately twice that of traditional PTFE/ceramic laminates, facilitating
heat removal.
Since
TMM3 is based on thermoset resins, and do not soften when heated. So wire
bonding of component leads to circuit traces can be performed without concerns
of pad lifting or substrate deformation.
