Awọn ẹgbẹ meji

Double-sided printed circuit boards work much like single-sided printed circuit boards, but are sandwiched between conductive layers on both sides. In addition, they are designed to have holes drilled into the plate.

These holes are placed on the board to allow the circuit to be mounted on either side of the PCB or fed through the board. Additional flexibility and conductive surfaces allow double-sided materials to be used in more advanced applications.

Sinu

Rigid PCBS can be single, double, or multi-layered. Rigidity tọka si ohun elo sobusitireti lati eyiti a ṣe awọn igbimọ. When a PCB is rigid, it is, as the name implies, made of materials that resist distortion or deformation.

A very common rigid PCB is the motherboard on a computer. Wọn ṣe apẹrẹ lati jẹ ti o tọ ati pe o le ṣee lo ni ipo kan ati apẹrẹ.

Rigid PCBS benefit from ease of maintenance and ease of use. Gbogbo awọn iṣẹ akanṣe ni ipo kan ati pe wọn ti samisi kedere nigbati wọn ṣe apẹrẹ. Wọn ti wa ni ko ni opin si ọkan oniru ati ki o le ibiti lati nikan Layer si mẹwa (10) Layer PCB awọn aṣa.
