RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Your Trusted Alumina/AlN PCB Manufacturer

Shenzhen, China - June 22, 2021 - Ceramic PCBs are the printed circuit boards using ceramic as the substrate. PCBONLINE provides alumina PCB, aluminum nitride PCB, COB LED (chip on board), DOB LED (drive on board), 3D aluminum products, etc. These types of circuit boards are used for high-power electronic modules, automotive electronics, aerospace, military electronics, high-power LED lighting products, etc.

Compared with the normal FR4 and metal core PCBs, ceramic PCBs have these advantageous characteristics:

  • Stable shape warping and low expansion coefficient
  • Large current carrying capacity and good insulation performance
  • Higher thermal conductivity and lower thermal resistance
  • Stable high-frequency performance and lower AK and DK values
  • Have good insulation and can achieve a better conductivity and insulation effect
  • Strong chemical stability

PCBONLINE adopts the advanced DPC (direct platting copper) technology to manufacture ceramic PCBs, which can realize three-dimensional circuit design. Depending on the thermal conductivity requirements of the ceramic PCBs, PCBONLINE adopts the normal lamination method and high-temperature sintering lamination method to manufacture multilayer ceramic PCBs. With its strong capabilities, PCBONLINE provides the best quality ceramic PCBs to engineers/solutions companies/research institutes/business makers.

 


Why Should You Choose PCB Assembly from PCBONLINE?

  • We test functionality (FCT) of PCBA to ensure product quality.
  • Our assembly quality is also ensured by first article inspection and 3D-scanning AOI.
  • Our reflow soldering ovens can process both lead-free and lead-containing soldering.
  • We can mount electronic components on a single side and double sides of advanced circuit boards.
  • We check your BOM carefully before assembly and offer free DFM/DFX.
  • We manufacture and assemble PCBs from prototypes to mass production.

 

About PCBONLINE

PCBONLINE E-ecosystem is an electronic manufacturing online purchase service created by GLOBAL SUCCESS GROUP. We found that the future business trends will focus on customization, and the traditional standardized PCB production line has been unable to meet the R&D of high-end electronic products and "fully meet" customer requirements and lose competitiveness. PCBONLINE provides differentiated services to our customers by means of the parent company's long history in high-end PCB manufacturing and Internet tools. We mainly serve high-end electronics manufacturing (EMS), such as the National Defense Research Institute, aerospace, communications and medical electronics We will continue to grow with the society and our customers so as to adapt to the changing world and value, and always provide the best PCB and EMS services.
