Ordering PCBs from fabricators in PCB Design - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the first step when ordering PCBs from a fabricator?

The first step is to prepare and verify your PCB design files, usually Gerber files, ensuring they meet the fabricator's specifications.

beginner

Why is it important to check the fabricator's design rules before ordering?

Because each fabricator has specific limits on things like minimum trace width and spacing, which affect manufacturability and cost.

intermediate

What information do you typically provide to a PCB fabricator besides Gerber files?

You usually provide the board thickness, copper weight, solder mask color, surface finish, quantity, and any special instructions.

intermediate

How does panelization affect PCB ordering?

Panelization groups multiple PCBs into one larger panel to optimize manufacturing efficiency and reduce cost.

intermediate

What is the role of a Bill of Materials (BOM) in PCB fabrication and assembly?

The BOM lists all components needed for assembly, helping fabricators source parts and assemble the PCB correctly.

What file format is most commonly used to send PCB designs to fabricators?

A Gerber files

B PDF files

C JPEG images

D Excel spreadsheets

Gerber files contain detailed layer information needed for PCB manufacturing.

Which factor does NOT typically affect the cost of PCB fabrication?

A Screen resolution

B Solder mask color

C Board thickness

D Number of layers

Screen resolution is unrelated to PCB fabrication costs.

Why might you choose a HASL (Hot Air Solder Leveling) surface finish?

A To make the board flexible

B For a gold-plated finish

C For better solderability and lower cost

D To increase board thickness

HASL provides a solderable surface and is cost-effective.

What does panelization help with in PCB manufacturing?

A Improving electrical performance

B Increasing the number of layers

C Changing the board color

D Reducing manufacturing cost by grouping boards

Panelization groups multiple PCBs to optimize production and reduce cost.

What should you verify before submitting your PCB order?

A Number of team members

B Design rule compliance

C Type of soldering iron

D Screen resolution

Ensuring your design meets fabricator rules avoids manufacturing errors.

Explain the key steps involved in ordering PCBs from a fabricator.

Think about what files and information the fabricator needs.

Describe how panelization can impact PCB manufacturing cost and efficiency.

Consider how fabricators produce many boards at once.
