How to improve the reliability of PCB? This question often troubles engineers. The reliability of PCB directly affects the performance of various applications, especially in harsh environments.
In this article, we will explore key strategies to improve PCB reliability in harsh environments, focusing on design considerations, materials selection，manufacturing techniques，and encapsulation.
Design Considerations
PCB raw materials will continue to increase in price in 2021
PCB raw materials include copper foil, fiberglass, resin and other related materials have been reported of price adjustments in Q1 of 2021.Recently, from CCL factory to PCB factory, we have received notices about product price increase.Even PCB industry has fired the first shot,
Seven steps of LED switching power supply PCB circuit board design.
In the switching power supply design, if the PCB board design is incorrect will lead to too much electromagnetic interference.There are seven PCB design steps will great stable power supply.Through the various steps in the need to pay attention to
PCB surface finishing OSP is abbreviation of Organic Solderability Preservatives. It grows a layer of organic film on clean bare copper surface through chemical method.This layer film has features like anti-oxidation,heat shock,moisture resistance, it can protect the circuit board copper don’t be oxidized or vulcanized,etc.But the protective film must be
PCB industry is technology-intensive,capital-intensive,labor-intensive industry.A middle scale factory have thousands workers, most of automatic machines need worker pile line operation.This years Chinese government impel corporation upgrade the structure of industry and the new labor contract law implement,lead to PCB factory face labor cost raise sharply and shortage,then impact production plan,products
PCB surface treatment ensure circuit board had good solderability or electrical property.Due to the nature of the copper oxide form tend to be in the air, it’s impossible to maintain the original copper,so copper requiring additional processing. Below is the most popular PCB surface treatment.
HASL and HASL-LF
HASL is hot air
