Splet15. nov. 2024 · 1. What is the basic information of PTH in PCB? Printed Circuit Boards electrically connect electronic components through conductive pathways, tracks or signal traces that are etched onto a copper-plated sheet. The PCB board itself is made of a non-conductive substrate and has several holes drilled through it. SpletAbout ten years later, the plating through hole (PTH) technology was developed, which allowed copper to be plated on the walls of drilled holes. With the PTH technology, the double-sided PCB could be produced with inter-connection through the holes. During the 1980s, with the growth in industry and technology, PCBs became more and more …

SpletThe through holes in a PCB undergo some plating, hence the term PTH. Plated through-holes have a conductive path moving from one side of the PCB to others. 2. Types of … SpletThere are three common types of drilled holes in the printed circuit board: PCB through hole plating, blind via hole, and buried via hole. Therefore, PCBs are classified according to drilling methods and can be divided into plated through-hole PCB, blind via hole PCB, and Buried via hole PCB.
