Printed Circuit Boards

What is a PCB Silkscreen on Printed Circuit Boards?

If you grew up taking apart radios, computers, or video game consoles just to see how they worked, you’ve likely studied a printed circuit board (PCB) up close. Among the intricate metallic traces and soldered components, you might have noticed small white letters, numbers, and symbols printed across the board’s surface. These markings aren’t random—they’re part of a critical layer called the PCB silkscreen.

Understanding the PCB Silkscreen Layer

The PCB silkscreen is a printed layer that provides human-readable information on a circuit board. Typically created with special inks, the silkscreen identifies important features such as:

  • Component reference designators (like R1, C5, U2)

  • Test points

  • Warning symbols

  • Company logos

  • Part numbers and date codes

  • Polarity indicators for diodes, LEDs, and capacitors

Most PCB silkscreens are printed in white ink because it contrasts clearly with the traditional green solder mask. However, silkscreen inks can also be black, red, blue, or yellow, depending on the board’s color scheme or specific customer requests.

Why Is the Silkscreen Important?

The silkscreen acts as a visual guide for anyone who assembles, repairs, or tests the PCB. It tells workers how components should be placed and identifies key features to assist in troubleshooting and maintenance. Without a clear silkscreen, identifying the purpose or placement of components could quickly become confusing, leading to costly mistakes or longer assembly times.

Additionally, the silkscreen enhances safety by marking high-voltage areas or other hazards clearly.

How Silkscreens Are Applied

Printed Circuit Board FabricationAdding the silkscreen is typically the final step in PCB fabrication, done while the boards are still panelized. The ink used must be carefully chosen to withstand the chemicals and heat involved in soldering and assembly. Once printed, the board moves to the final finishing or routing phase.

There are several methods for applying a silkscreen:

  • Manual Screen Printing: Traditional, cost-effective for low-volume runs

  • Liquid Photo Imaging (LPI): Offers higher precision for dense, complex boards

  • Direct Legend Printing (DLP): Uses inkjet printers for extremely accurate and fast printing

Each method is selected based on the PCB’s design complexity, production volume, and budget.

Common Mistakes to Avoid in Silkscreen Design

Even experienced PCB designers can make mistakes when preparing the silkscreen layer. Some key things to watch out for:

  • Avoid printing over pads: Silkscreen ink can interfere with soldering and create defects.

  • Keep text legible: Fonts should be large enough to read easily, even after solder mask application.

  • Allow for registration tolerance: Slight shifts during manufacturing mean text and symbols should have enough spacing to stay clear and readable.

A well-designed silkscreen makes the PCB easier to work with and improves overall product quality.

How to Choose the Right Printed Circuit Board for Your Application

Printed Circuit Boards (PCBs) are at the heart of nearly every electronic device we use today—from smartphones and medical monitors to aerospace controls and industrial machines. Choosing the right PCB for your specific application isn’t just about picking the cheapest option—it’s about ensuring your product functions reliably, efficiently, and safely.

So how do you know which type of PCB is right for your needs? Let’s walk through the key factors to consider when selecting a PCB during the PCB Fabrication process.

Printed Circuit Board Fabrication1. Understand Your Application Requirements

Start by clearly identifying the role the PCB will play in your device. Ask yourself:

  • Will the board be used in a high-temperature environment?
  • Does it need to be flexible or rigid?
  • Will it handle high frequencies or power loads?
  • Are there space constraints or weight limits?

Understanding the physical and functional demands of your application will help guide your PCB design, material choices, and layout.

2. Choose the Right Type of PCB

There are several types of Printed Circuit Boards, each serving different purposes:

  • Single-sided PCBs – Great for simple, low-cost electronics like calculators and toys.
  • Double-sided PCBs – Common in consumer electronics where moderate complexity is needed.
  • Multi-layer PCBs – Ideal for high-performance, compact designs like smartphones, servers, and aerospace tech.
  • Rigid PCBs – Best for durable, permanent structures.
  • Flexible PCBs – Perfect for wearables, medical devices, or curved applications.
  • Rigid-Flex PCBs – Used in high-performance electronics that require both flexibility and strength.

The right type depends on both your performance needs and your product’s design limitations.

3. Select the Proper Materials

In PCB Fabrication, the choice of materials affects durability, conductivity, heat resistance, and cost. Common materials include:

  • FR-4 – A widely used fiberglass-reinforced epoxy laminate; affordable and versatile.
  • Polyimide – Offers better flexibility and heat resistance, great for aerospace and military uses.
  • Ceramic – Provides high thermal conductivity and is used in high-frequency or high-power applications.

Choosing the right substrate and copper thickness is crucial to match your performance and environmental needs.

4. Consider Signal Integrity and Thermal Management

For applications involving high-speed signals or high power, signal integrity and heat dissipation become critical. Your PCB layout, trace widths, spacing, and use of thermal vias must be optimized to prevent overheating and maintain performance.

This is especially true for industries like automotive, aerospace, and medical—where failure isn’t an option.

5. Work with an Experienced Manufacturer

Your PCB is only as good as the partner who fabricates and assembles it. At BoardAssembly.com, we specialize in high-quality PCB Fabrication tailored to your application’s unique needs.

Wire Harness

ACME PCB Assembly Wire and Cable Harness Services

It is important to understand that a wire harness is different than a cable harness.  A wire is a single conductor, while cables are two or more wires that are insulated being wrapped in a larger jacket. These two technologies demand their own set of unique tools, fixtures, and machinery to help reduce production costs. Knowing exactly what type of product being used is crucial to perfectly create your designs.

Wire harnesses generally do not need much to work with and is generally an inexpensive and cost-efficient way for many people to solve their electrical needs. With a single machine, one can increase their production capabilities because of the relative simplicity of wires in general.

A wire harness is a method that incorporates several point-to-point cable assemblies together into one conclusive assembly.  They are generally held together using cable ties or some form of protective sleeve used to protect the wires or cables from environmental conditions like moisture, heat or friction, and to organize the different breakouts for easy routing through a system or box build.

What Can Wire Harnesses be Used For?

Though you might confuse a wire harness for a cable assembly, there is one main difference and that is a wire harnesses usually contains several ends or breakouts, running in different directions, serving multiple functions with multiple terminations on each breakout.

A custom wire harness can be used in durable goods like household appliances, in and around engines of all kinds – automobiles, buses, locomotives, trucks, and even planes.  Electronic equipment, construction machinery, industrial equipment, HVAC products all use wire harnesses as well.

Located in Carson, California, ACME PCB Assembly utilizes top of the line technology from Schleuniger to perfectly cut, strip, and process any wire or cable you need.
