Double Sided PCB Introduction

Manufacturers produce two-layer PCBs by placing copper layers on both sides of a single substrate layer. Typically use techniques such as etching to remove excess copper. and drilling to insert any necessary vias that connect the two layers. This process allows for the creation of circuits that are more complex than those possible with single-layer PCBs. but less so than those made with multi-layer PCBs.

Double Sided PCB Advantages

Two-layer PCBs offer several benefits. Firstly, they provide a higher circuit density than single-layer PCBs. without the cost associated with multi-layer PCBs. They also allow for easier routing of electrical pathways. which can result in more efficient designs. Additionally, two-layer PCBs often enhance the electromagnetic compatibility . by providing a ground plane to reduce noise and interference.

Ordering Double Sided PCB Process

ensure a smooth and efficient prototyping process, here’s what you should provide:

  1. PCB Design Files: As mentioned, supply all necessary design files in a universallyaccepted format like Gerber RS-274X. Ensure that these files are complete and accurate.
  2. Specifications and Requirements: Clearlyspecify your material preferences. board thickness, copper weight, surface finish (like HASL, ENIG, etc.), and any other specific requirements. This helps in producing a PCB that meets all your functional needs.
  3. Assembly Drawings (if applicable): If your prototype needs to include assembly. provide detailed assembly drawings. This includes the placement of components, types of components. and any special soldering or assembly instructions.
  4. Test Requirements: If there are specific electrical tests you need. such as impedance control or continuity checks, provide these details. This ensures that the final product functions as intended.
