PCB Materials Choosing the appropriate printed circuit board material is crucial in today's world of sophisticated electronics, cutting-edge technology, downsizing, and ever-increasing signal speed. The suitable high-quality materials will produce a circuit board that not only performs but adequately lasts…
What Is FR-4 Material? The flame-Retardant fiberglass-reinforced epoxy compound is known as FR4 material by the NEMA (National Electrical Manufacturers Association). When soldering, your circuit board is shielded by this substance from other elements and heat. A layer of FR4…
What are 02 Layer and 04 Layer PCBs? 02 Layer On both sides of the printed circuit board, conductive copper and components can be mounted using a two-layer PCB, allowing the traces to cross over. Consequently, it results in a…
What is Solider Mask Expansion: Purpose and working?The significant support to the initial pad/via shape to generate the desired solder mask layer shape. If you provide a positive value, the initial pad/via shape will expand; if you enter a negative value,…
