ROHS (Restriction of Hazardous Substances Directive, Restriction of Hazardous Substances Directive) and CE (Conformité Européenne, European Conformity Mark) certification are important regulations and certifications related to the manufacturing and sales of electronic products. The following are the general steps for ROHS and CE certification process in PCBA assembly:

The typical turnaround time for circuit board assembly produced through contract electronic manufacturing can vary depending on several factors, such as the complexity of the assembly, the quantity of boards required, and the specific requirements of the project. Generally, the lead time for simple and small scale projects with fewer components and simple designs is 2 to 3 weeks. For more complex projects with higher component count, special requests for the manufacturing process, or any extra testing, the lead time could be 4 to 6 weeks or more. However, many contract electronic manufacturing service providers offer a rush service with accelerated delivery times of 1 to 2 weeks for an extra fee.

In the field of PCBA processing, high reliability test is a key link to ensure the quality and stability of circuit boards. This article will discuss high reliability test in PCBA processing, including test principles, common test methods, test process and its importance.

Optical microscopy inspection in PCBA processing (Printed Circuit Board Assembly) is a critical quality control step that can effectively detect issues such as component installation, soldering quality, and surface defects on the circuit board. This article will delve into the optical microscopy inspection in PCBA processing, including its role, inspection methods, and advantages.

With the continuous popularization of various types of electronic products in the information age, the production scale of printed circuit boards as component carriers is also expanding, and about 18 billion square meters of circuit boards produced around the world each year. And more and more new circuit boards are produced and used, which means that a large number of old circuit boards are scrapped and eliminated. Generally speaking, the circuit board will be processed and recovered.

In PCBA design, effective thermal management strategies are essential, especially for high-performance, high-power or high-temperature applications. The following are design strategies for heat sinks, heat sinks, and fans:
