Unimicron

Unimicron is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Unimicron rather than just read about it. In short: Unimicron Technology Corporation (Unimicron; TWSE: 3037) is a printed circuit board (PCB) manufacturer headquartered in Taiwan. The company produces PCBs, high density interconnection (HDI) boards, flexible PCBs, rigid flex PCBs, integrated circuit (IC) carriers, and others.

Key takeaways

Unimicron belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Unimicron to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Unimicron from memory before moving on to harder problems.

Reference excerpt

Unimicron Technology Corporation (Unimicron; TWSE: 3037) is a printed circuit board (PCB) manufacturer headquartered in Taiwan. The company produces PCBs, high density interconnection (HDI) boards, flexible PCBs, rigid flex PCBs, integrated circuit (IC) carriers, and others. In addition, it provides testing and burn-in services of IC substrates and PCBs. Applications of its products and services include liquid crystal display (LCD) monitors, personal computers (PCs) and peripheral products, notebook computers, network cards, facsimile machines, scanners, mobile phones, personal digital assistants (PDAs), and others. Unimicron has manufacturing sites and/or service centers in Taiwan, China, Germany, and Japan.

Overview Unimicron, a subsidiary of United Microelectronics Corporation, started in 1990, grew to global rank of 6th in 2006, and became global No. 1 in the PCB industry in 2009 and 2010. Unimicron arrived at a second position in the 2012 global PCB market with a market share of 3.7% and $2.4 billion in revenue.

Worked examples

Example 1 — a first encounter with Unimicron

Start with the simplest possible case. Write down what Unimicron claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Unimicron before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Unimicron ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Unimicron

In research: Unimicron appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Unimicron in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Unimicron is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Taoyuan City, Electronics companies established in 1990, Printed circuit board manufacturing, so understanding it makes those chapters shorter.
In everyday life: Look for Unimicron outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Unimicron in simple terms?

Why does Unimicron matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Unimicron?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
