How to choose PCB (Printed Circuit Board) material?

PCB material must be chosen entirely on the basis of a balance of design requirement, volume production, and cost. Electrical elements that need to be taken into account during high-speed PCB design are called design demands. In addition, the frequency should be taken into account when determining the dielectric constant and dielectric loss.

Is There Any Minimum Order Quantity(MOQ) Requirement for PCB or PCB Assembly Order?

Typically, there is no minimum order quantity (MOQ) for a new order, even if you can order one piece.

Which Factors Affect PCB Cost?

The following listed are the key factors but not limited:

  • The quantity and size of the PCB.
  • The Number of Layers
  • Effective Panelization– Some board sizes and shapes can offer up to 80% Usable Panel Area, with very few “dead spaces”, while others come down to 50%. This would affect your price.
  • A number of holes in the boards are drilled on sophisticated NC drilling machines. These machines are quite expensive, and the machine time is expensive too, so fewer holes mean less machine time for drilling and lower cost.
  • A number of Hole Sizes– the slowest operation in drilling is the tool exchange. Usually, the boards are drilled at very high RPM values, up to 60-80.000 rpm. To change the tool, the machine has to stop the spindle, so we must wait until the tool stops rotating. Once the drill action has stopped, the machine must move to the drilling rack, replace the old tool, get a new tool, move back to the board drill position, drive the spindle again, and wait for the RPM value to reach the set point for the new tool. Each tool change takes approximately the same time as drilling 100-200 holes. Try to minimize the number of drill tools as much as possible. It is best to standardize any holes with diameter differences of only a few mils, if the change will pass your required tolerances.
  • PCB Laminate Material – when you intend to manufacture your board in volume, the right choice for the board laminate can save a lot of money. For instance, despite the superior characteristics of FR-4, all consumer electronics today still is manufactured on old paper FR-2 laminates as they cost two times less expensive than FR-4.
  • Trace Width / Part Spacing Requirements – these characteristics are closely related to the manufacturing yield. For instance, if your traces are wide enough (>20mils), the board can be manufactured with etch-resist single silkscreen printing operation instead of dry film lamination, exposure, and development.
  • Special board requirements, Controlled Impedances Via in Pad, Blind / Buried Vias, Microvias, etc., affect the manufacturing yield.
Do You Provide Free PCB Samples?

Yes, we provide Free PCB samples, and the qty is no more than 5 pcs. But we need to charge the samples first and return the PCB sample cost in your mass production if your sample order value is not more than the mass production value’s 1%.

Are All of Your PCBs RoHS Compliant?

Yes, we don’t provide leaded PCBs for environmental protection and corporate social responsibility. All of our materials, chemicals, and processes are RoHS-compliant. For HASL surface finish, we only provide lead-free HASL.

What Are Your Capabilities of PCB Fabrication?

We have capabilities for manufacturing most custom PCBs, and we list our PCB manufacturing capacities for all kinds of PCBs we can fabricate on our website.
