Do you want to learn how to repair PCB?
Learn essential PCB repair skills: fix lifted pads, damaged traces, solder bridges, and corrosion using multimeters, micro-soldering, and inexpensive kits. Revive electronics and save money with step-by-step guides.
What does the solder mask do?
Solder masks prevent PCB shorts/corrosion. Learn color tradeoffs (green, black, red, blue, white), LPI vs dry film types, UV application steps, and quality defect fixes.
What are the steps for PCB testing?
Avoid PCB failures with systematic testing: design reviews, environmental stress analysis, component verification. Match methods to complexity, ensure durability, and fix costly errors efficiently.
What is FR4 Material?
FR4 PCB material delivers affordable reliability with balanced electrical insulation, heat resistance & manufacturability. Master dielectric constant, Tg, CTE & design for cost-effective performance.
What is the red glue on the SMT PCB?
Red glue is a heat-solidifying polyolefin adhesive used in SMT to fix components during wave soldering. It prevents detachment in mixed DIP/SMD PCB assembly processes. Usage declines with advanced soldering techniques.
What are the differences between FPC, PCB and SMT?
Essential guide to SMT workshop operations: PCB/FPC materials, environmental controls (temp/humidity), solder paste handling, process flow, ESD protection, quality systems & standards for efficient electronic assembly.
PCB board thickness classification and how to choose? Choose the right one and save tens of millions of costs!
PCB thickness (0.3-4.0mm) impacts mechanical strength, thermal performance, signal integrity, & cost. Standard is 1.6mm. Choose ultra-thin (0.2-0.8mm), thick (2.4-3.2mm), or standard based on application & budget.
FPC flexible PCB processing technology knowledge
FPC flexible printed circuit boards are vital in electronics, classified as single/double-sided or multi-layer. They use key materials like FCCL, cover film, adhesive film, and copper foil, manufactured via sheet-by-sheet or roll-to-roll processing.
Understand the relationship between layout and PCB in one article
Master PCB layout to minimize switching power supply EMI. Key strategies: reduce high di/dt & dv/dt loop areas, implement loop cancellation, optimize grounding schemes, shield noise sources, and partition circuits effectively.
Do you know the basics of PCB component packaging?
Master PCB component packaging basics: types (DIP plug-in vs. SMD surface mount), common packages for diodes, capacitors, resistors, and ICs, essential elements (pads, outline, silkscreen), and Allegro file suffixes to prevent design errors.
