Whats the Difference Between SMD and NSMD? SMD and NSMD are two types of semiconductors. While their pads are similar in size, NSMD components have smaller dimensions. In contrast, SMDs can be moved by the soldering iron, while a through-hole component can be mechanically secured prior to soldering. NSMD pads are smaller There are several […]
The Most Common PCB Defects and Its Solutions There are many problems with PCBs, but some of them are less obvious than others. These problems are called implementation failures and require specialized knowledge to diagnose. For example, Electrostatic discharge, Chemical leakage, Lifted pads, and component shifting are all possible causes of failure. To identify the […]
5 Factors Impacting Quality of SMT Soldering Several factors impact the quality of SMT soldering. These include equipment state, Solder paste quality and Stability. Understanding these factors will help you improve your SMT soldering processes. The best way to improve the quality of SMT soldering is to implement improvements in every area. Stability In a […]
Hvordan PCB-materiale med høj termisk ledningsevne vil løse problemet med varmeafledning PCB'er, også kendt som printkort, er lagdelt struktur bestående af kobberfolier, der er indlagt mellem glas-epoxylag. Disse lag tjener som mekanisk og elektrisk støtte for komponenterne. De højledende kobberfolier fungerer som det ledende kredsløb i PCB'et, mens [...]
2 Notes on PCB Reverse Engineering Computerized tomography A computerized tomography is a powerful tool for reverse engineering PCBs. This technique uses x-rays to take images of the inside of a circuit board. The resulting image can be used to reconstruct the board’s structure. Computerized tomography has several limitations, however. Its field of view is […]
Things to Know Before Ordering a PCB Project If you are going to order a PCB project, there are a few things that you should be aware of. For instance, you must double check your traces before ordering. In addition, you need to make sure that your BOM and drill file match. Moreover, you must […]
How to Know the Surface Finish From PCB Color If you’re wondering how to know the surface finish of a PCB, you’re not alone. The color of a PCB can reveal its surface finish. You may also see a color designation called ENIG or Hard gold, Silver, or Light red. Regardless of what you see, […]
Tips to know about Semi-Flexible FR4 Printed Circuit Boards FR4 is a flame-retardant material Printed circuit boards made from FR4 are extremely durable. However, the cost of these boards is higher than the ones made from other materials. In addition, these boards tend to delaminate easily, and they emit a bad odor when soldered. This […]
How to Do the PCB Board Array Panelize Process Embedded board arrays can be panelized to reduce manufacturing costs. This article discusses the different options available, including using a laser-cutter, a saw, or a router. The first step is to design the board on its own. The design must include the table and dimensions for […]
