Potting vs Conformal Coating of PCB Assemblies Conformal coatings are a protective, non-conductive dielectric layer that are added to a circuit board or electronic device. A coating “conforms” to the object being coated (often referred to as the “substrate”), allowing protection without significant additions to the weight or thickness of the device. Potting is also […]
Following the double whammy of the US-China trade war and the COVID-19 pandemic, an increasing number of global manufacturing companies are looking to shift parts of their supply chains, including PCB and electronic PCBAs, from China to India, according to multiple recent reports. Many companies have suffered significant disruptions to their supply chains as authorities across the […]
The first article inspection process is a critically important step in the manufacturing process of your PCBA. When your PCBA assembler sets up your design and the assembly process required to produce units to your defined specifications, the first boards are generally considered as “first article” production. “First articles” are not prototypes or PCBA pre-production […]
Printed Circuit Board Designers deal with an array of challenges, from electrical, functional, mechanical, production, quality and price. To avoid some common problems, Design for Manufacturability (DFM) considerations should also be factored into the design process. Some of the most common DFM problems are discussed below, along with some alternative considerations. Footprint Geometry Try to refer […]
One way is to use a standard convention such as the Association Connecting Electronics Industries, or IPC Standards. The IPC is a global trade association for the electronic interconnect industry (www.ipc.org) covering design, Printed Circuit Board manufacturing and electronics assembly. Specific topics covered include: Acceptance, Fabrication, Flexible Circuits, General, High Density / Fine Pitch, High Speed / […]
Prior to the start of Printed Circuit Board (PCB) manufacturing, engineers review all drawings, specifications and files to ensure manufacturability. Any identified concerns or issues or communicated back to the customer for clarification or correction. Once complete and all issues or concerns are resolved, the first step of the manufacturing process is to release material to […]
Copper Thickness The most common measurement unit for copper thickness on a Printed Circuit Board (PCB) is ounces (oz). How thick is that? It’s the thickness when 1 oz of copper is spread evenly over a one foot square area. It equals 1.37 mils (or 1.37 thousands of an inch). For other common units of measure, consider: […]
The growth rate of LED Assembly related technologies has been on an exponential and continuous rise among end-users, developers and manufacturers. The popularity is a result of low energy consumption, high-efficiency, versatility in design and applications, and small dimensions. A variety of companies specialize in the design, manufacture and assembly of systems based on light-emitting diodes (LED), […]
Intematix LED Assembly refers to the production of Solid State Lighting products that feature patented phosphor technology from the Intematix Corporation. Phosphor, a material that is luminescent, is crucial for a wide range of lighting applications, particularly for LED’s. The majority of all LED’s are blue LED’s covered in a coating of phosphor. Benefits of Intematix LED […]
Rebel Star Assembly refers to the production of products comprised of Rebel Star LED’s (light-emitting diodes) pre-soldered onto a metal core printed circuit board (MCPCB) base. Benefits of Rebel Star Assembly Rebel Star High Power LED’s (HP LED’s) have the ability to be driven by currents ranging from hundreds of milliamps (mA) to over 1 amp. Some HP LED’s […]
