Potting vs Conformal Coating of PCB Assemblies
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 […]
Shifting Supply Chains from China to India
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 […]
PCB Assembly, First Article Inspection Process
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 […]
DFM Hints for PCB Design
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 […]
How can Printed Circuit Board Manufacturers, Customers, and Suppliers speak the same language?
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 / […]
PCB Manufacturing
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 […]
Printed Circuit Board – 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: 1 oz […]
Solid State Lighting Assembly
Generally considered assemblies constructed of light sources emitted via solid-state electroluminescence via PLED’s (polymer light-emitting diodes) or LED’s (light-emitting diodes) instead of gas, plasma (fluorescent lamps), or electrical filaments (incandescent lights). Benefits Solid State Lighting Assemblypresent many notable advantages over compact fluorescent (CFL) or incandescent lighting technologies. Benefits in terms of energy savings and environmental […]
US-China Trade War Fears?
The Trump Administration’s recent announcement that a second -round of Chinese imports COULD BE targeted for tariffs have electronic end products squarely in their sights. While it’s not at all clear to the general public if the published list of $50 billion dollars-worth of goods (and 1,300 end-use items) will experience tariffs, it’s good to […]
Long Lead Times for Electronic Components Continue
The current electronic component shortage primarily caused by MLCC’s continues to cause OEM’s serious problems and according to Industry Insiders, there is no end in sight to this problem (Ref:https://www.ttiinc.com/content/ttiinc/en/resources/marketeye/categories/passives/me-zogbi-20180302.html) MLCC Shortages Are Creating Challenges In Multiple End-Markets in 2018 03/02/2018 // Dennis M.
