PCB boards are usually composed of multiple layers stacked together, with each layer performing a different function. The following are common PCB layers and their meanings: Signal layer: The signal layer is one of the most important layers on the PCB board. It contains the signal transmission path between electronic components and realizes signal transmission […]

1.Incoming Inspection Incoming inspection refers to the confirmation and verification of the quality of purchased raw materials, components, or products, that is, the quality is inspected through sampling when the supplier sends the raw materials or components, and the final judgment is made whether the batch of products is accepted or rejected. 2.Meaning IQC is […]

What is PCB stackup? Under normal circumstances, when designing ordinary single or double-sided boards, there is no need to consider the lamination problem of the PCB. Usually, a copper-clad board with a copper thickness and a plate thickness that meets the design requirements is directly selected for direct processing. However, when designing a PCB with […]

After the SMT patch proofing of the SMT small batch patch processing factory is completed, some follow-up processing procedures, such as testing, assembly, etc., are required. After all the electronic processing links are completed, it is delivered to the customer. It is relatively easy to be disturbed by various factors in the delivery and transportation […]

Every PCB assembly manufacturer must adhere to proper cleaning standards. Now the appearance of the circuit board cleanliness requirements are more and more strict, without affecting the work of the board, our DYC factory has been working hard to deliver a clean circuit board to each customer。   1.Comply with IPC-5704 All medical device development […]

TWELVE BEST PCB DESIGNING SOFTWARE TOOLS In the market there is a large variety of PCB design software available. Some are proprietary, some are free to use online, and others are industrial grade PCB software. The following is a list of software EDA tools which PCB HERO Inc has compared for their performance. ALTIUM DESIGNER […]

On the test board, the components are placed in two directions, 0 ° and 90 °. Determine whether component orientation (0 ° and 90 °) significantly affects the yield of assembly by analyzing paired samples. The 0 ° direction indicates that both ends of the component pass through the furnace simultaneously, while the 90 ° direction indicates […]

According to the PCB design process, after the PCB layout was completed, a rigorous review process is required to determine whether the designed product meets the ESD or EMI requirements. Excluding schematic design, PCB design generally required to review both layout and wiring. DYC Electronics will introduce EMC design suggestions for PCB layout.   EMC […]
