This PCB guide center collects practical articles about PCB design, fabrication, soldering, testing, supplier selection and manufacturing checks. Use it as a starting point when you need to prepare files, compare production options, inspect a board problem, or talk with a PCB supplier. Manufacturing and supplier selection pcb china manufacturer Read more
Learn how to manufacture PCB board from Gerber files through imaging, drilling, plating, solder mask, silkscreen, surface finish, inspection, and DFM checks.
Learn how to print silkscreen on PCB with legend layers, pad clearance, useful markings, manufacturing limits, readability checks, and DFM review.
Learn how to protect PCB from moisture with design spacing, conformal coating, masking, cleaning, storage, inspection, and DFM review.
Learn how to read PCB layout files by checking board outline, layers, components, traces, vias, drill files, silkscreen, and DFM issues before fabrication.
Electrostatic discharge is one of the most underestimated threats in PCB manufacturing and repair. A technician walks across a carpeted floor, reaches for a circuit board, and unknowingly delivers thousands of volts through a fingertip. The board passes testing. It ships to the customer. Three months later, it fails in Read more
Drilling is one of the most fundamental processes in PCB manufacturing, and the method you choose directly affects cost, board density, reliability, and manufacturability. Two technologies dominate the field: mechanical drilling, which uses carbide or diamond-coated bits to physically cut through the board, and laser drilling, which uses focused energy Read more
Learn how to measure PCB trace impedance with TDR, test coupons, stackup data, tolerance checks, and controlled impedance DFM review.
Learn how to make vias on PCB with drilling, copper plating, via types, annular ring checks, aspect ratio limits, and DFM notes before fabrication.
Learn how to tell how many layers a PCB has using edge inspection, vias, light checks, stackup clues, and when to ask a manufacturer for confirmation.
