  Minimize the number of layers if possible. Each additional layer increases manufacturing complexity and cost. Consider a 2-layer or 4-layer board for simpler designs to reduce expenses. Proper planning of the layer stack up ensures impedance control and signal integrity but may add complexity, so a careful balance needs to be struck based on application needs.
• Panelization
  Panelize your PCBs, which means arranging multiple copies of your board on a single panel. This is especially cost effective for mass production and assembly. Manufacturers can fabricate and assemble multiple boards simultaneously, reducing cost. Consider using standard panel sizes to avoid incurring additional setup fees.
• Material Selection
  Choose standard materials like FR-4 for most applications. Advanced materials like Rogers can increase the cost considerably. Assess the actual needs of your design, and if standard materials meet the required performance criteria, opt for them to reduce material costs. Be aware that choosing alternative materials might have implications on manufacturing processes and thus cost.
• Component Selection
  Utilize standard components rather than custom or rare parts whenever possible, as these are typically more readily available and cost-effective. Standard components also often come in larger production runs, which contributes to lower per-unit prices. Avoiding hard-to-source components will also reduce procurement times and potential delays in your production cycle.
• Via Optimization
  Minimize the number of vias used in your design. Using blind or buried vias will increase cost. Using standard through-hole vias wherever possible will reduce complexity and cost. Careful routing will reduce unnecessary vias.
• Trace Width and Spacing
  Use standard trace widths and spacing if possible. These are easier to manufacture and will avoid additional costs. Minimum trace widths and spacing often require higher fabrication accuracy and could drive costs up. Consult your manufacturer's capabilities and standards to achieve a balance between density and cost.

Beyond the Quote: Considerations for PCB Manufacturing

While obtaining a PCB quote is a crucial first step, a holistic view of PCB manufacturing extends beyond just the price tag.
