Why are PCB Boards for Medical Devices mostly Double-sided?

In terms of medical equipment and technology, the medical industry is growing rapidly. These devices and technologies require printed circuit boards (PCBs) to include complex designs, robust structures and huge power. When medical companies contact PCB manufacturers to meet these requirements, PCB vendors usually recommend two-sided printed circuit boards for medical equipment applications. What makes this PCB type an ideal solution for medical equipment?


PCB double panel has become the ideal solution

As the name implies, a double-sided PCB consists of a dielectric layer with two copper circuit layers on both sides. Copper layer is further protected by solder mask layer. This design helps PCB designers to improve PCB layout in a variety of ways, including:
Both the top and bottom layers can be used for through-hole routing.

Traces can be closer together and more numerous.
Circuit board edges can be electroplated to improve grounding and shielding connections.
Copper with a thickness of more than 140 microns and up to 3.2 millimeters can be used in PCB structures.

Types of double-sided PCB

In addition to these points, PCB manufacturers can also use double-sided circuits to create different types of PCBs. These types may include:
Soldering tin coating PCB
Fine wire surface mounting PCB
Construction of PCB with ultra-high copper
High and low temperature PCB
Understanding the advantages of two-sided PCB
Design solutions offer a variety of benefits to PCB manufacturers and customers.
Relatively low cost
Higher circuit density
Complexity of intermediate circuit
More flexible in design
Reduce circuit board size (reduce cost)

These differences confirm the application of double-sided PCB in medical applications. This type of PCB can support the operation of medical equipment, such as hand-held blood tester, chest wall oscillation system and deep brain stimulation system. Through the above explanations, do you think that double-sided PCB boards are the most used in medical equipment? Of course, there are many sophisticated medical equipment, using more sophisticated circuit boards, which is required for functions.
