we will discuss where you can get 3D models and download STL files for free. While many models are available to purchase, there are plenty of free models and STL files you can get for free. It’s an easy, time-saving way to get started on your 3D model adventures.

In the TV series Westworld, scientists have already been able to print simulated human tissues with 3D Printing technology. Cooperated with AI technology, creating a realistic human being became a reality. Although this only happens in science fiction now, it may come true one day in the future. No one knows.

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. 

Mechanical switches are the core of every mechanical keyboard. They are responsible for creating their unique feel, sound, and even the smoothness of typing. One of the reasons why plenty of typists and gamers prefer mechanical keyboards and switches is that they can customize them.

Elecrow is a professional expert who can meet the requirements of PCB assembly, PCB manufacturing, PCB layout, PCB prototyping and PCB rework. Elecrow has a mature system and various testing methods to ensure manufacturing your PCBA with high quality. 

The Raspberry Pi is a very cheap computer that runs Linux, but it also provides a set of GPIO (general purpose input/output) pins, allowing you to control electronic components for physical computing and explore the Internet of Things. Crowpi-L is a real Raspberry Pi computer for learning programming and hardware. Crowpi-L is a real Raspberry pi laptop for learning programming and hardware.

Elecrow collected several common process defects in PCBA processing to help you to avoid detours. Learn these PCBA process defects and get twice the result with half the effort in the design phase.
