Aluminum is the most common material used for metal printed circuit boards. Standard PCBs are not made of metals; instead, they are made of materials like FR4, fiberglass, ceramic, polymer, etc.
To facilitate signal conduction, these circuit boards contain copper layers, silkscreen, and soldered masks. They can be single or double-sided boards based on the application requirements.
Most companies create a PCB prototype in the design and testing phases of their projects. When you are ready to move to the production phase, you will want to use the standard PCB service.
While the prototype PCBs are used to test and finalize designs, the standard PCBs are the printed circuit boards that will be installed in your products.
Standard PCB service refers to the full-feature PCB manufacturing process. With over ten years of providing PCB manufacturing services, we have handled numerous projects and covered almost all sorts of substrate materials, including FR4, Aluminum, Rogers, and others. Unlike prototype PCB services, our standard printed circuit board services have strict production limits.

MKTPCB is a full-service turnkey PCB manufacturer that handles everything from prototype to full-production to assembly.
We have been manufacturing high-quality standard boards for more than ten years. Besides, we are fully compliant with ISO, IPC, and RoHS standards. Our standard circuit boards are IPC 2 compliant, and we conduct a thorough internal quality inspection to ensure that our final products are of the highest quality standards.
At MKTPCB, we are obsessed with quality, and we always aim for a flawless design and functionality of our PCB products. We have laid out a 5-step quality inspection procedure to ensure our products are 100% functional.
MKTPCB acknowledges FAI as the initial step of quality inspection before the mass production of circuit boards. We put up this step to avoid producing large quantities of defective products due to processing and operational issues.
We inspect every resistor, capacitance, and inductance using an LCR meter. Besides, we use QC with BOM and Assembly drawing to verify chips.
The AOI process verifies the placement of electronic components and solder joints after SMT. The primary objective is to get the highest quality control and detect and remove defects in the earlier stages of the assembling process.
In this step, we use short wavelengths of 0.0006-80nm to penetrate various PCB materials. Designs with BGA and QFN packages have solder joints that are not easily visible by human eyes. We employ X-ray machines to inspect such packages in the final printed circuit board assembly.
After carrying out FAI, AOI, and X-Ray inspections, our quality engineers conduct the last visual quality inspection process for all products. This process ensures that products have gone through all the assembling processes and are of good quality.
Finally, we also conduct functional tests on all automated test equipment to simulate different loads, typically average, peak, and abnormal loads. This is a complicated process that involves various tool-based and programming tests. Additionally, this step requires customer technical support.
MKTPCB remains committed to providing the best quality standard PCB manufacturing services – both prototype standard PCB manufacturing and standard PCB manufacturing at competitive prices.
This commitment has helped us emerge as the trusted and reliable provider of standard PCB fabrication services in China. We have an experienced team of experts and a state-of-the-art infrastructure that guarantees high-quality products in a quick turnaround.
