关于PCB电气测试您需要了解的内容 为何要在PCB制造过程中开始进行电气测试 在PCB板的生产过程中，很难避免由外部因素引起的短路、断路和漏电等电气缺陷。此外，PCB正不断向高密度、细间距以及……

为了提高PCBA的生产效率、降低生产成本，通常会将PCB电路板进行拼板处理，以便进行电路板组装生产，这不仅能方便PCBA的焊接，还能节省时间。PCB拼板的目的是什么？提高SMT组装的效率。拼板中包含的电路板数量越多，……

关于PCB过孔的必知知识 电路板由多层铜箔构成。电路的不同层通过孔（VIA）相互连接。电路板的作用是导电，因此这种孔被称为通孔。PCB过孔的类型 镀通孔……

电路板的制造是一个耗时的过程，通常并不被视为“简单的事”。尽管有些爱好者只要备齐所需材料，就能在家中自制电路板，但这些自制电路板通常比机器制造的要简单一些。此外，这也会相当耗时……

本文主要面向初学者，介绍PCB焊接知识，并讲解如何运用几种不同的技术对各类元器件进行焊接。虽然PCB焊接起初看起来可能令人望而生畏，但一旦尝试，你会发现它在大多数应用中其实很容易上手。在焊接电路板时，应首先检查PCB的……

高频PCB是一种具有高电磁频率的特殊印刷电路板。 在PCB领域中：高频是指频率大于300MHz或波长小于1m的频率，微波是指频率大于3GHz或波长小于0.1m的频率。高频PCB是一种采用……工艺制造的电路板。

Pcb circuit boards are widely used in various industries such as electrical appliances, computers, mobile phones, and computers. It is the main part of electronic components. However, circuit boards have a powerful enemy – pcb corrosion. A circuit board that strong acids or other chemicals have corroded will not be able to continue working. Corrosion…

Ball grid array (BGA): The process of replacing all the solder balls on a chip’s ball grid array is called BGA rebound. BGA packages have become very popular in the printed circuit board (PCB) design and manufacturing industry. These packages help reduce the size of a PCB and improve its functionality. BGA can withstand the…

PCB designers use digital design automation to generate a design frequently. The EDA app stores layout info, facilitates editing the plan, and automates repetitive design tasks. The very first phase is converting the circuit schematic to a web list. The web listing gives component hooks and the circuit structures or baits that every pin connects….

If that’s the case, use a magnifying glass or low-power microscope. Cracks or stains in any solder ought to be noted. Assess all holes. When none-plated through holes have been given, make certain this is the situation on the plank. Poor plating through pockets can lead to a brief circuit between layers and lead to…
