[PCB Information Network] FPC, also known as Flexible Printed Circuit, has a significantly different PCBA assembly and soldering process compared to rigid circuit boards. Due to the insufficient hardness and flexibility of FPC boards, without using dedicated carriers, it is impossible to complete basic SMT processes such as fixing, transmission, printing, and placement. 1. Pre-treatment … Read more
SMT Top Networking Circle A professional circle for sharing networking resources and achieving career advancement. New Platform 2020 1. FPC Preprocessing FPC boards are relatively soft and are generally not vacuum packaged when leaving the factory. They are prone to absorb moisture from the air during transportation and storage, so they need to undergo a … Read more
Similarities and Differences between Cold Soldering and Open Soldering1.Similarities Cold soldering and open soldering exhibit many similarities in their manifestations, which often leads to misidentification in practical work. Therefore, accurately identifying the similarities and differences between cold soldering and open soldering is crucial for quality control in electronic product manufacturing. The similarities between cold soldering … Read more
SMT, short for Surface Mount Technology, originated in the 1960s, involves directly mounting SMD components onto PCBs. Its greatest advantage is the high wiring density per unit area of each component, which shortens connection lines and improves electrical performance. Below, I will quickly guide you through the SMT process flow. (This is SMT) 01 SMT … Read more
Abstract: This article introduces a very old PCB manufacturing process – the etching method. The advantages of this process include low cost and short time. However, there are also significant drawbacks, such as the complexity of making double-sided boards and environmental concerns! The specific manufacturing method is as follows: Designing the PCB 1. Design the … Read more
I picked up the soldering iron and started hand-soldering the board~~It can be described as clumsy, but the result is acceptable; the entire circuit is connected.Tomorrow, I will secure everything to the box and re-flash an ESP32 program to start the experiment. Let’s go!
1. Introduction Today, I came across a method shared online for creating a DAP-LINK using the AT32F425 microcontroller. I happen to have this microcontroller on hand, so I will test the DAP-LINK creation method shared online. I usually use DAP-LINK as a development tool for ARM microcontrollers, so creating this development tool can also be … Read more
