PCB stands for Printed Circuit Board. A PCB is a board used to mechanically support and electrically connect electronic components using conductive pathways or traces etched from copper sheets laminated onto a non-conductive substrate. PCBs are the foundation of almost every electronic device, allowing...
● Usually, the inner layer of copper will be removed by chemical etching● The photoresist keeps the necessary copper on the board safe from etching● The time and solvent required for etching may vary depending on the size of the boards● Larger boards often require more time and/or solvent...
DPC ceramic PCB stands for Direct Plated Copper ceramic Printed Circuit Board.It is a type of printed circuit board that uses a ceramic substrate instead of a traditional fiberglass substrate (FR4). The ceramic material offers better thermal conductivity and electrical insulation properties,making it ...
The FR in FR-1 material stands for fire retardant, which is a property of a material to extinguish fire itself. Throughout their lives, the PCBs went through a lot of heat and even sometimes, the components get a spark and catch fire. Hence, in such circumstances, the fire-extinguishing...
ENIG stands for Electroless Nickel Immersion Gold. It is also referred to as immersion gold or soft gold. The ENIG process is quite similar to ENEPIG. This process involves depositing Ni-P alloy on a Pd surface. Manufacturers use the displacement reaction to achieve this process. Also, they ...
The term FR4 stands for flame retardant, and the number 4 designates a rating that distinguishes the material from others. FR4 is described as a woven, and thin fiberglass-reinforced epoxy laminated sheet used in the production of PCBs. The substance’s FR4 composite fiberglass structure is what...
After a thorough cleaning, the panel goes through consecutive chemical baths. Around 0.08 to 0.1 micron thick copper layer gets deposited on the hole barrel as well as the surface of the panel. Electroless copper deposition 10. Outer layer imaging We used photoresist on the panel for inner-...
A rough copper foil texture can enhance the adhesion of resin to copper, which is essential for RCC to function properly. Resin Resin, the other essential component of RCC, is a thermosetting polymer that provides mechanical and chemical stability to the circuit board. There are different types...
In Printed Circuit Boards, OSP stands for Organic Solderability Preservative, which mainly applies to copper pads. It selectively bonds to copper to prevent it from tarnishing on exposure to moisture. PCB OSP surface finish is environmentally friendly, given its lead-free material, and requires low...
FR stands for “flame retardant” and indicates that the material is compliant with the UL94V-0 standard on plastic material inflammability. The 94V-0 code can be found on all FR-4 PCBs. It guarantees the non-propagation of fire and its rapid extinguishing when the material burns. ...
