When it comes to a printed circuit board (PCB), selecting the right material, stackup, and construction details can make all the difference. In this article, we will provide an overview of a specific PCB that utilizes RT/duroid 5880 PTFE Random Glass Fiber material and has a 2-layer rigid stackup.
The PCB Material is RT/duroid 5880. This material is known for its high performance, low loss, and lead-free composition, making it more environmentally friendly. It can operate within a temperature range of -40℃ to +85℃.
The stackup for this 2-layer rigid PCB consists of a finished copper thickness of 35um, an RT/duroid 5880 dielectric thickness of 31mil, and another finished copper thickness of 35um. The finished board thickness is 0.9mm, and the finished copper weight is 1 oz (1.4 mils) for all layers.
The via plating thickness is 1 mil, and the surface finish is Electroless Nickle Immersion Gold (ENIG). There is no top or bottom silkscreen or solder mask, and there are no silkscreen on the solder pads.
Regarding construction details, the PCB has a dimension of 195mm x 182mm, with a tolerance of +/- 0.15mm. The minimum trace/space is 4/7 mils, and the minimum hole size is 0.25mm. There are no blind or buried vias, and the PCB has undergone 100% electrical testing to ensure its quality.
The PCB contains 54 components, 91 total pads, 39 thru-hole pads, and 52 top SMT pads, with 43 vias and 12 nets. This design uses PCBDOC artwork, and it conforms to the IPC-Class-II standard.
