Phenolic Printed Circuit Boards Tutorial – Gregtech CEu

In this comprehensive guide, we’ll walk you through the process of crafting phenolic printed circuit boards in Gregtech CEu. This is the easiest circuit board option for reaching medium voltage, and we’ll cover every step from creating silver wire to assembling the final product.

Introduction to Phenolic Circuit Boards

The phenolic printed circuit board is your gateway to medium voltage progression in Gregtech CEu. It’s the simplest circuit board option available and serves as an excellent stepping stone in your tech tree. Let’s break down the production process into manageable steps.

Creating Silver Wire

The first component you’ll need is silver wire. At low voltage, you’re limited to using a wire mill to process your silver ingots. Simply configure the wire mill to process one silver ingot, which will yield two silver wires.

Once you progress to medium voltage, you have access to simpler machines like an extruder for this task. However, at the low voltage stage, the wire mill is your only option.

Setting Up Your Power Infrastructure

Before assembling circuit boards, you need a reliable power source. You can use a creative energy source for testing, but in a real playthrough, a basic steam turbine generator will suffice.

Pay close attention to amperage when routing power through cables. You can monitor amperage by looking at your cables directly—they display current draw (for example, 1.5 out of 2 amps). This information is crucial because exceeding the amperage limit will burn away the cable’s rubber coating. However, exceeding voltage limits causes machines to explode, which is far worse.

Producing Wood Pulp with the Basic Massorator

Wood pulp is one of two main ingredients needed for phenolic circuit boards. To produce it, place oak logs into a basic massorator. This machine will convert the logs into wood pulp.

To automate the export process, access the massorator’s configuration menu. Click and drag to navigate the interface, then double-click on the “auto” option on the side where your item pipe connects. This enables automatic export of wood pulp directly to your assembler.

Creating Glue Using the Basic Centrifuge

The second ingredient is glue. Set up a basic centrifuge and feed it sticky resin from rubber trees. The centrifuge will produce liquids that flow downward and raw rubber pulp as a byproduct.

To extract the glue properly, click on the machine’s output sides to configure them. Make sure to enable auto-output for the liquid by clicking the appropriate button. The liquid outlet is located at the bottom of the machine—this is a common point of confusion, so verify you’re using the correct output. Connect a fluid pipe from the centrifuge directly to your assembler.

Assembling Phenolic Printed Circuit Boards

Now that you have wood pulp and glue flowing into your basic assembler, you’re ready to craft phenolic circuit boards. You’ll also need silver wire, which you produced earlier with the wire mill.

If your assembler isn’t producing boards despite having all materials present, check the circuit settings. You must configure the circuit to “1” in the assembler settings—this is a critical step, as the recipe specifically requires one program circuit. You can verify this requirement by checking the recipe in JEI, which displays “1 in program circuit.”

Final Product and Next Steps

Once your assembler produces the phenolic printed circuit boards, combine them with silver wire to create your finished good circuits. This completes the easiest path to medium voltage progression in Gregtech CEu.
