Today we bring you a complete version of the production process for circuit boards, hoping to give you a deeper understanding of circuit board production! Cutting materials Purpose: According to the requirements of the engineering data MI, cut into small pieces of production boards on large sheets that meet the requirements. Small pieces of boards that meet customer requirements Process: Large plate material → Cutting according to MI requirements → Curing plate → Rounding corner/grinding edge → Plate discharge Drilling Purpose: Based on engineering data, drill the required hole diameter at...

Assuming that the frequency of a digital logic circuit reaches or exceeds 45MHz~50MHz, and the circuit operating above this frequency occupies a certain proportion of the entire electronic system (such as 1/3), it is usually called a high-frequency circuit (multi-layer circuit board). High frequency circuit board planning is a very chaotic planning process, and its wiring is crucial to the entire planning! First move, wiring of high and multi-layer circuit boards High frequency circuits often have high integration and high wiring density. Choosing multi-layer circuit boards is not only...

What inspections are needed during the production process of printed circuit board to reassure customers? Many customers worry about quality issues when selecting suppliers. Today, the editor of Weifu PCB circuit board will share with you how we inspect circuit board at every stage of the entire production process? Interested friends, don't miss out! Firstly, incoming inspection: acceptance inspection of raw materials, auxiliary materials, outsourced parts, and purchased parts before entering the factory for storage. Ensure that unqualified materials are not stored or used. Secondly, there is...
