4.Why should you purchase from Uniwell?

The answer is simple. You may already be aware, but most PCB manufactures sell to you through an extended supply chain. i.e. Manufacturer –> Distributor –> Dealer –> Salespeople –> Customer
Each link in that chain adds to the overall cost of your equipment. The end result is you wind up paying way more than you should.
Uniwell Circuits has changed all that. We simply manufacture and sell direct to you. Providing you with a high value, top quality product that is easy to self-install and easy to buy, direct.
Because we are a true factory direct manufacturer, we have no sales outlets or dealers that ultimately add additional cost to our prices.  We are looking forward to establish long term cooperation with you!

5.Little knowledge--- Radio frequency PCB

Development of communication technology has witnessed gradually wide applications of wireless radio frequency (RF) circuit such as in the fields of mobile phones, Bluetooth products and RF circuit has been the core technology of radio propagation. In recent years, however, the gradual prevalence of 4G and obvious increase in terms of data's transfer order of magnitude lead to challenges to PCB design of RF circuit. After all, the number of signals transferred by RF circuit escalates by hundreds of times every day. Furthermore, since RF circuit is mainly applied in portable devices that have attributes of small scale and portability, the basic requirement of the whole circuit lies in small volume, even and reasonable routing and non-interference between micro components. Nevertheless, it seems unavoidable that electromagnetic interference takes place between components inside mobile phones. Don't worry. Some operations can be applied to effectively reduce the influence caused by electromagnetic interference.
