Types of PCB Aspect RatioHelp Your Business Grow


We ensure that the Multilayer PCB Aspect Ratio is appropriate for the application of Multilayer boards. This is how we create 5G PCBs to make digital connectivity easier.

Press-fit PCB Aspect Ratio

Residue-free and solderless PCB assembly is possible with the correct Press-fit PCB Aspect Ratio. Other advantages of Press-fit PCBs include their use in high-voltage applications and gadgets.


Using a 1:1 aspect ratio for Microvia PCB Aspect Ratio simplifies Wireless PCB design. It’s also easier to maximize multilayer boards with Microvia and Ball Grid Array.

20 Layer CTI PCB

Buried Via PCB Aspect Ratio is especially important for multilayer boards. It enables lightweight solutions to give consumers the ability to access the internet on the go.

Copper Foil VT-47 PCB

PCBMay has so far produced excellent Blind Via PCBs. Outer layers are precisely coupled with a board’s inner layer when Blind Via PCB Aspect Ratio is correctly implemented.

Multilayer CTI PCB

PTH PCB Aspect Ratio is utilized so that plating solution flows efficiently through the hole. To account for this, the assure that PCB drill hole tolerance is calibrated accurately.

We Only Deliver the Correct PCB Aspect Ratio

As long as you have us as your partner, there is no limit to our ability to design your PCB. We show off our facilities and fabrication process in this video to give you a good idea of our PCB Aspect Ratio competence.
