The burn-in board is a loaded board used for the high-temperature aging test. PCB aging board means that some component parameters on the circuit board will change after the circuit board is powered on for a certain period under certain conditions. This change is related to the use time of the circuit board, which is […]
IWR1642 BOOST is an easy-to-use 77GHz millimeter wave sensor evaluation board for IWR1642 devices that can be directly connected to a microcontroller (MCU) development kit equipped with millimeter wave tools and software, including mmWave Studio (MMWAVE-STUDIO) and millimeter wave software development kit (MMWAVE-SDK).
Semi-curable sheet is a major category of products sold as commodities in the PCB FR-4 copper clad plate industry. When making multilayer printed boards, PCB factories use it to bond the prepared inner boards. Previously, the production of multilayer printed circuit boards required at least two semi-cured sheets for each layer, so that the resin […]
The copper plating quality of printed circuit board is closely related to the application reliability of printed circuit board. With the development of printed boards to high density and high precision, the requirements for copper plating are also higher and higher. It is not only required that the coating is uniform and fine, but also […]
Selection of SMT steel mesh manufacturing process and materials What is the SMT mounting price? What is the manufacturer's calculation based on? Is a pad a point? How much is a point? Today, Hengtian Weiye Technology will give you a comprehensive introduction to the SMT price calculation method! SMT mounting is to mount electronic components […]
1. Bare Copper Advantages: low cost, flat surface, good solderability (without being oxidized). Disadvantages: easily affected by acid and humidity, can not be stored for a long time, need to be used up within 2 hours after unpacking, because copper is easily oxidized when exposed to air; can not be used for double-sided boards, because […]
Microwave PCB belongs to high-frequency PCB, also known as RF PCB. Mainly used in fields such as wireless communication, wireless networks, and satellite communication. With the development of technology, the demand for microwave PCB design continues to grow, and microwave PCBs are gradually entering other fields, becoming the main products in multiple fields such as […]
The Development History of the PCB Board Before the emergence of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. In contemporary times, circuit boards only exist as effective experimental tools, while printed circuit boards have become a dominant position in the electronics industry. […]
The Production Process of Rigid PCB The production process of PCBs with different difficulty levels and layers may vary slightly, but can be summarized as the following steps: 1. Cutting: Cut out easy to process dimensions from a large sheet of copper clad plate with a certain thickness and copper foil thickness. 2. Drilling: Drill […]
