Elecrow is running an awesome giveaway for fans with 8 sets of brand new Raspberry Pi Pico Advanced Kit from 8/22-9/15.
During the PCB manufacturing process , there will be a process that covering the surface of the pad with a layer of material to protect the pad from oxidation. The common PCB surface treatment processes are: HASL (Hot Air Solder Leveling), OSP (Organic Soldering Preservative), Immersion Tin, Immersion Gold, Immersion Silver and so on.
PCB is one of the basic components of the electronics industry. These printed circuit boards are applied to enable electrical interconnection between various components. PCBs are divided into diverse categories on different purposes, and this article will dive into the common classifications and features of different PCB types.
PCBs are the basis of most modern electronic devices. They have wiring and pads connecting individual points together. It takes 6 steps to fulfill the whole PCB manufacturing process. Now, we will introduce them one by one through pictures.
Designing is the first step in PCB manufacturing. Generally speaking, it involves 10 aspects: PCB thickness design, laminated structure design, inner graphic design, borehole design, outer circuit design, solder mask design, PCB form factor design, PCB multi-pieces splicing design, V-CUT design and PCB thermal design.
