What is High TG In PC Board Fabrication?
The making of PCB involves different steps, technologies, and terms, and TG is one such term that refers to the Glass Transition Temperature. High TG PCB is the board made at a high temperature. We will discuss this topic in detail, including the TG value, features, applications, materials, parameters, and much more. What is High TG PCB? If a PCB’s temperature goes beyond a set TG value, its condition will change. Like, the solid board will turn rubbery, affecting a PCB’s function. Depending on where you use a PCB, the temperature of the application should be at least 10 to 20C less ...
PC Board Fabrication, V-Scoring-Purpose and Benefits
PCB or a printed circuit board [1] has different holes, cuts, and elements, and V-scoring is one of them. V-scoring pre separates the PCB and designers also call it V-groove because a groove resembling V is cut on the circuit board’s top and bottom. Generally, the depth of the groove is 1/3 of the board depth and there is a thin layer between two Vs for the board processing. The boards with V-grooves are either end to end or side by side with adjacent edges. The groove helps break boards with a little force, and you can divide a single panel ...
PCB fabrication using green Soldermask?
How to use green Soldermask in pcb fabrication [1]. As we know that printed circuit boards are the building blocks of electronic devices. It is not wrong if we say that the electronic industry is relying on the quality of printed circuit boards in order to provide better functionality and performance. Now let us move forward with the fact that the printed circuit board [2] is something we need to understand first if we are talking about electronics. Maybe you have seen one in your computer or other commonly used gadgets. What color came to mind? Let me guess! Is it ...
How To Choose High-Frequency PC Board Materials For Your RF Microwave Project?
The high-frequency PCB material is based on using a synthetic thermoplastic fluoropolymer which has an excellent dielectric property at different smaller microwave frequencies. For the design of PCB circuits with microwave frequencies, important characterizations that determine laminate circuit performance include dielectric constant (DK), dissipation factor (Df), thermal expansion coefficient (CTE), thermal dielectric constant coefficient (TCDk), and thermal conductivity. The most known high-frequency material for users of PCB laminates may be polytetrafluoroethylene (PTFE), a synthetic thermoplastic fluoropolymer with outstanding dielectric characteristics at microwave frequencies. PCB applications include RF antenna, WiFi (Carrier-Green and Licensed Access), IP infrastructure, power amplifiers, diplexers/multiplexers, testing, measurement, etc. It ...
What is a Gerber Viewer in PCB Design?
[gallery ids="683"] Gerber Viewer A Gerber viewer is any software application that enables you to examine the contents of a Gerber file. While some of these applications need installation, others are available online and do not require downloading or installation. All you have to do to see your Gerber files online is upload them. Gerber files Before the establishment of Gerber files, there were no industry-standard guidelines for manufacturing printed circuit boards (PCB). The papers that included the Printed Circuit Board [1] requirements contained a diverse range of information. There have been many instances of miscommunication and misunderstanding between consumers and manufacturing firms. Finally, ...
