Definition of multilayers
Multilayer PCBs, or multilayers for short, are PCBs that have additional inner layers. In contrast to simple PCBs with only two outer layers, multilayers contain several…
Example of the resistance of a 100mm wide conductor with a length of 100mm on the inner layer
Copper thickness Conductor diameter Line resistance
18µm ≙ 1.8 mm² 0.0012 Ohm
35µm ≙ 3.5 mm² 0.0006…
The prices for 4-layer multilayer prototypes have been significantly reduced. This is made possible by the continuous use of AI (artificial intelligence) in PCB production preparation and the…
For PCBs that are exposed to high thermal loads, it is important to determine the required maximum operating temperature (MOT) in good time in order to determine a suitable material.
The maximum…
CTE-z
The CTE value shows the thermal expansion of the base material. CTE-z represents the z-axis and is e.g. due to the stability of the vias, of high importance. A higher Tg value favors a low…
Tg Value
The glass transition temperature (Tg) is an important normative dimension for the base material that determines the temperature at which the resin matrix converts from a glassy, brittle…
