If we cut the dielectric thickness in half the capacitance doubles.

Thin pcb laminate. Choosing the right laminate is crucial as it determines stability lower loss and optimum performance of the final assembly. Note that chips are routinely thinned to less than 0 1mm in thickness so the height of the chip is similar to that of the pcb laminate material. According to the thickness of the copper clad laminate it can be divided into conventional board and thin board. Thin laminate sheets 0 2mm fleece back wood veneers from china 2description.

For a six layer foil lamination the best standard to be used should be 062 10 or 031 10 respectively. After bonding i d then encapsulate the implant chip in an epoxy similar to the epotek 301 resin shipped with precursor for security sealing to protect the wirebonds then polish back any excess epoxy material so there is a smooth void free surface. Several laminate options are available to support the assembly of printed circuit boards. These laminates offer significantly improved electrical performance over standard fr4 and often a combination of fr4 and a high speed laminate may be preferable to an alternative fr4 material.

The epoxy resin ccl having a thickness excluding copper foil thickness of less than 0 8 mm is generally referred to as the thin board ipc standard is 0 5 mm. Fr4 tends to have higher losses than other printed circuit board pcb materials that are specialized for rf applications. Thin laminate sheets are our popular decorative fancy fleece backing and paper backing wood veneers. A one inch square power ground pair of the popular 50um 2 mil buried capacitance laminate produces approximately 450 pf of capacitance.

The gml1100 thin core copper laminate is just such a material. If the foil lamination is for a four layer pcb the standard to be used should be 031 10.

Our main wood veneer products include man made wood veneer natural veneers paper back veneer fleece backing veneer splicing matched veneer wrapping profile veneer and veneer edge banding. If we double the dielectric thickness the capacitance goes down by a factor of two. This blog familiarizes you with the four commonly used pcb laminate materials read more.
