Applications of Prototype PCBs

  • ● PCB prototyping provides samples for bulky production in case the design has defects
  • ● Small batch manufacturing for business makers and research institutes to sell/test designs
  • ● Ceramic PCB prototypes are used for applications that require good thermal conductivity, such as lasers, automotive sensors
  • ● Flexible/rigid-flex PCB prototypes are used for devices with a compact space that has flexibility requirements, such as satellites
  • ● High-frequency PCB prototypes can be used for RF/high-speed applications, such as radars, antennas
  • ● Aluminum PCB prototypes can be used for power modules and LED lights, such as automotive front lights

PCB Prototype Manufacturing and Assembly

  • PCB prototyping is pre-production before bulky fabrication, and the quality should be the same as bulky fabrication. At PCBONLINE, when we receive Gerber/IPC-2581 files from you, our engineers review your documents, if anything needs improvement, we suggest it, and then we give a quote to you. When you also review and agree to fabrication, we manufacture the PCB prototypes.
  • The prototyping process varies according to different designs, but always includes laminate pre-treatment, inner circuit generation, drilling, lamination, external circuit etching, solder mask printing, and surface finishing. If you also need PCB prototype assembly, we make an SMT stencil and source electronic components during PCB manufacturing.
  • The PCB prototype assembly happens on our SMT lines and THT lines. The assembly process includes solder paste printing, solder paste inspection, high-speed surface mount, functional surface mount, reflow soldering, AOI inspection, through-hole mount, wave soldering, functional inspection, and aging test. If you require, we can also conduct conformal coating.

Prototype PCB Order Pooling

PCB prototyping process
The unit price of PCB prototypes is higher than batch production. If you need better budget control, you can have PCB prototyping in the order pooling way. PCB order pooling means grouping different prototype PCBs on the same production panel. Only if the PCBs require the same manufacturing process can be grouped. Relying on a large number of orders, we can provide order pooling to reduce your PCB prototyping cost.
PCB order pooling is optional. We still suggest single PCB prototyping for the best quality, especially if your boards are complex PCBs used for aerospace, defense, medical, automotive, communication, industrial, and research.

Advantages of PCB Prototypes

  • The total area of prototype PCBs is only 0.2㎡ and the required components are also in a small quantity, so PCB prototyping is fast. The advantages include:
  • ● PCB prototypes enable developers to test different designs in a short time period at the smallest costs.
  • ● PCB prototypes allow further optimization in bulk manufacturing and enhance product performance.
  • ● Provide free one-on-one engineering support, DFM, DFT, and DFX to make sure your design is free from defects.
