Qualities and Characteristics of 6 oz Copper PCB PCBTok (1)

PCB is the most important part of any electronic device. It is the circuit board that connects all the components and provides them power.

The PCB industry has seen a lot of changes over the years, especially in the last decade. With more companies trying to find new ways of manufacturing PCBs, there have been many breakthroughs in this area.

One such breakthrough is using 6 oz copper as a material for making PCBs. The use of this material has made it possible to manufacture thinner PCBs while also increasing their strength and durability.

6 oz Copper PCB Production

PCBTok 6 oz Copper PCB’s Standard Inspection Process

PCBTok offers a wide array of services. We ensure that all our clients get their orders fulfilled on time and with excellence by sticking to the standard inspection process. The process is outlined below:

  • Sample Inspection: Before any order is placed, samples are inspected for quality assurance.
  • Assembly: After sample inspection, PCBs are assembled into panels and tested for functionality and performance.
  • Final Testing: Final testing involves testing each component individually before assembling it into a panel and then testing it again after assembly to make sure they function properly.
Choose Your 6 oz PCB’s Surface Finish

When you’re ordering your 6 oz PCBs, there are a few different surface finishes that you can choose.

One option is ENIG (Electroless Nickel Immersion Gold). This is a very durable finish that helps prevent corrosion and abrasion. It’s a great option if you’re planning to use your boards in the outdoors or for something that will be around for a long time.

Another option is HASL (Hot Air Solder Leveling). This is our most popular choice because it gives good performance and doesn’t require much maintenance.

OEM & ODM 6 oz Copper PCB Applications


Aerospace Technology PCB’s Surface Finish can be offered in several different finishes. The process used to produce the base surface is Immersion Tin and Copper Plating.

Power Distribution
