What is the difference between circuit design and circuit board design?

Starting from today, let's introduce the introduction of circuit board design.

The purpose is to let everyone design some simple circuit boards by themselves. At the same time, we can review the omission of knowledge in the design.

As for the expert level, you can skip my article. Because of the limited time every day, I hope you can forgive me.

Let's talk less and get to the point.

In other words, how did we get into this industry. (is it a digression

It's because the school didn't learn the knowledge well and didn't distinguish what is circuit design and what is circuit board design.

It is because of this, suddenly deviated from their own destiny. Let's do circuit board design, boss. Good drop good drop to answer, full of brain thought is the circuit design.

So what is the difference between circuit design and circuit board design?

Circuit design: electrical circuit and electronic circuit design. The circuit is mainly divided into digital circuit and analog circuit.

Digital circuit that can be said to be everywhere, the most common is the life of computers, mobile phones and home appliances. Analog circuit is more common in power supply, drive and industrial analog control. This paper only talks about electronic circuit design.

The simple and crude explanation is that the symbols of resistance, capacitance and other electronic components learned in school are connected by wires, which is circuit design.

Circuit board design: according to the circuit drawing (concept) completed by circuit design, the plane design of circuit board is completed. The designed data is passed to the circuit board manufacturer, and the circuit board can be produced.

Speaking of this, just interested in circuit design friends please detour, so as not to waste valuable time.

Well, first of all, let's talk about the circuit board. Whether it's circuit design or circuit board design, it's for making circuit board services.

Give me a picture first

This should be a control class of small circuit board, the image is not very clear.

If you have time to open the back cover of the TV remote control, you can see the relatively simple circuit board more intuitively.

Brief introduction of PCB manufacturing engineering

Someone once asked me, is it necessary to have a deep understanding of the manufacturing process of circuit boards just for the design of circuit boards? Of course, it is necessary!!!

The reason is simple: Here's a metaphor. If the figure painters on the street do not fully understand the human body, then what a miserable painting you will be

First of all, the production of a four-layer board project, the program will be different due to the actual conditions of the manufacturer of the circuit board.

Because it's drawing on the gourd, if there are mistakes, we hope to correct them.

Because of the time, I will write here first, and then I will explain in detail the various links of the circuit board manufacturing process.
