What is the adhesive in flex PCB?
In flex PCBs (Flexible Printed Circuit Boards), adhesive layers are crucial for bonding the conductive copper layers to the flexible insulating substrate, which is typically made of polyimide or another flexible material. These adhesives provide mechanical stability while allowing the board to bend and flex without compromising performance. The Common Types of Adhesives Used in […]
What is the maximum layers in flex PCB?
What is the maximum layers in flex PCB? The maximum number of layers in a flex PCB (Flexible Printed Circuit Board) can vary depending on the complexity of the design, material properties, and manufacturing capabilities. Typically, flex PCBs are available in configurations ranging from single-layer to multi-layer. Standard Layer Configurations: 1.Single-Layer Flex PCB: This is […]
The advantages and disadvantage of tent via, plugged via, and vias not covered?
The advantages and disadvantage of tent via, plugged via, and vias not covered? When deciding between tented vias, plugged vias, and vias not covered in PCB design, it’s essential to understand the advantages and disadvantages of each type based on factors like protection, cost, and the specific needs of the circuit. Here’s a comparison of […]
A Look Back at the 2024 Munich Electronica Exhibition
A Look Back at the 2024 Munich Electronica Exhibition Our company Dreamland Electronics, we attended the Electronica 2024 trade fair in Munich earlier this month was an unforgettable experience that left me both inspired and informed. Actually, if you are a company registered in China, this exhibition is sure to leave you with much to […]
What is Vias Not Covered on PCB Board?
What is Vias Not Covered on PCB Board? Vias not covered refers to vias (small holes in a PCB used to connect different layers or carry signals) that are left exposed or uncovered by solder mask or other protective layers. In this case, both the top and bottom of the via are open, revealing the […]
What’s plugged via on PCB Board?
What’s plugged via on PCB Board? A plugged via is a via hole in a PCB that is filled with a material—usually conductive or non-conductive epoxy-after the drilling process. This process is used to close the via opening for various technical or performance reasons. Unlike tented vias, which are simply covered with a solder mask, […]
What Is Tenting Via on PCB Board?
What Is Tenting Via on PCB Board? Tenting via is a process used in PCB fabrication where a protective layer of solder mask is applied over the top of vias (small holes that connect different layers of a PCB). This mask covers the via’s opening, either fully or partially, preventing it from being exposed to […]
What’s PCB assembly?
What’s PCB assembly? PCB Assembly (PCBA) is the process of mounting and soldering electronic components onto a Printed Circuit Board (PCB), transforming a bare board into a functional electronic circuit. It’s a critical step in electronics manufacturing, combining the physical structure (the PCB) with the necessary components to make the circuit work. What are Key […]
What is Fiducial Mark on PCB Board?
What is Fiducial Mark on PCB Board? The fiducial mark on a PCB (Printed Circuit Board) is a reference point used during the assembly process, particularly in Surface Mount Technology (SMT). These marks are critical for ensuring that the automated machines, such as pick-and-place robots or optical inspection systems, correctly align components on the PCB. […]
Do LED lights have circuit boards?
Do LED lights have circuit boards? Yes, LED lights often incorporate circuit boards, particularly Printed Circuit Boards (PCBs), as an integral part of their design. These boards serve as the foundation for mounting and electrically connecting the LEDs and other electronic components. Why LED Lights Use Circuit Boards? The Common Types of PCBs Used in […]
