A Standard PCB typically refers to a rigid printed circuit board made from FR4 material. It usually consists of a single layer, double layers, or multi-layers (up to 6 layers) with a standard thickness of 1.6mm (0.062″). Standard PCBs are the most cost-effective solution for consumer electronics, industrial controls, and general applications due to their mature manufacturing process.
Standard PCB Specifications vs. Custom Options
Choosing standard PCB specifications helps reduce manufacturing costs and lead times. Below is the matrix of our standard capabilities versus advanced options.
| Parameter | Standard Specification (Most Economic) | Advanced/Custom Option |
| Base Material | FR4 (Tg130-140) | High TG, Aluminum, Rogers |
| Board Thickness | 1.6mm (0.062″) | 0.4mm – 3.2mm |
| Copper Weight | 1 oz (35µm) | 2 oz, 3 oz (Heavy Copper) |
| Layer Count | 2, 4, 6 Layers | 8+ Layers |
| Surface Finish | HASL (Lead-Free) | ENIG, Immersion Silver, OSP |
| Min. Trace/Space | 6/6 mil | 3/3 mil |
| Solder Mask | Green | Blue, Red, Black, White |
| Silkscreen | White | Black, Yellow |
Why FR4 is the Standard for Rigid PCBs
FR4 circuit boards are the industry standard for a reason. Composed of woven glass-reinforced epoxy laminate, FR4 offers an excellent balance of mechanical strength and electrical insulation.
Tg Ratings: Our standard boards use TG130-140 materials, which are sufficient for most operating environments. For higher thermal stress, we offer High TG PCB options.
Surface Finishes: HASL vs. ENIG
Selecting the right finish is crucial for shelf life and solderability.
- HASL (Lead-Free Hot Air Solder Leveling): The most common and affordable finish for standard PCBs. Ideal for through-hole components.
- ENIG (Electroless Nickel Immersion Gold): A flat surface finish perfect for SMT (Surface Mount Technology) and BGA components, offering better oxidation resistance.
Manufacturing Standards: IPC Class 2 and Class 3
At PCBinq, “Standard” does not mean low quality. All our standard PCBs are manufactured in strict accordance with IPC-A-600 Class 2 standards.
- Class 2: Standard for dedicated service electronic products (Computers, Laptops).
- Class 3: Available upon request for high-reliability products (Automotive, Medical).

FAQ
The global industry standard thickness is 1.6mm (0.063 inches). This offers the best balance of durability and cost. Other common thicknesses include 0.8mm, 1.0mm, and 2.0mm.
A Standard PCB uses common materials (FR4), standard stackups, and finishes (HASL) to minimize cost and production time. Custom PCBs involve specialized materials, complex stackups, or non-standard thicknesses.
For general use, HASL (Lead-Free) is the most cost-effective standard finish. If you have fine-pitch components, ENIG is recommended due to its flat surface.
