Sure, here is a product description about Prototype circuit boards for sale, including the capability about board thickness, copper thickness, hole size, PCB surface finish, solder mask, PCB layer stack-up, and PCB material:
Prototype circuit boards are unpopulated printed circuit boards (PCBs) used for testing and developing electronic circuits. They are typically made from FR4 material, which is a glass-reinforced epoxy laminate that is strong, heat-resistant, and flame-retardant. Prototype circuit boards are available in a variety of thicknesses, copper thicknesses, hole sizes, surface finishes, solder masks, and layer stack-ups.
Board thickness
The thickness of a prototype circuit board is typically 0.63mm (25 mils), 1.0mm (40 mils), 1.5mm (60 mils), or 1.6mm (63 mils). The thicker the board, the more rigid it will be, but the more difficult it will be to solder components to it.
Copper thickness
The thickness of the copper foil on a prototype circuit board is typically 1 oz (35 microns) or 2 oz (70 microns). The thicker the copper foil, the more current it can carry, but the more difficult it will be to etch.
Hole size
The size of the holes on a prototype circuit board is typically 0.63mm (25 mils), 0.81mm (32 mils), or 1.0mm (40 mils). The smaller the hole size, the more difficult it will be to solder components to it.
PCB surface finish
The surface finish of a prototype circuit board is typically ENIG (electroless nickel immersion gold), HASL (hot air solder leveling), or OSP (organic solderability preservative). ENIG is the most expensive surface finish, but it is also the most reliable. HASL is a less expensive surface finish, but it is not as reliable as ENIG. OSP is the least expensive surface finish, but it is not as reliable as HASL.
Solder mask
The solder mask is a green or blue coating that is applied to the PCB to protect the copper traces from oxidation and to prevent the solder from bridging between traces.
PCB layer stack-up
The PCB layer stack-up is the order of the different layers of a PCB. A typical two-layer PCB will have a top layer of copper foil, a dielectric layer, and a bottom layer of copper foil. A four-layer PCB will have two additional layers of dielectric and two additional layers of copper foil.
PCB material
The most common material for prototype circuit boards is FR4. FR4 is a glass-reinforced epoxy laminate that is strong, heat-resistant, and flame-retardant. Other materials that can be used for prototype circuit boards include polyimide, ceramic, and metal.
When choosing a prototype circuit board, it is important to consider the following factors:
Once you have considered these factors, you can choose a prototype circuit board that is right for your needs.
