Until now, I have these two options: Excellent recommendation! Thanks for this, just what I was looking for to lay the foundation: I actually hear Dave's Australian accent when I read it. That's not weird, is it?

Martin Martin 6, 1 17 Featured on Meta. Unicorn Meta Zoo 3: How do we grade questions? Linked Thus was born the PCB. PCB is an acronym for printed circuit board. It is a board that has lines and pads that connect various points together.

In the picture above, there are traces that electrically connect the various connectors and components to each other.

A PCB allows signals and power to be routed between physical devices. Solder is the metal that makes the electrical connections between the surface of the PCB and the electronic components. Being metal, solder also serves as a strong mechanical adhesive. A PCB is sort of like a layer cake or lasagna- there are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object.

The base material, or substrate, is usually fiberglass. Historically, the most common designator for this fiberglass is "FR4". This solid core gives the PCB its rigidity and thickness.

There are also flexible PCBs built on flexible high-temperature plastic Kapton or the equivalent. Cheaper PCBs and perf boards shown above will be made with other materials such as epoxies or phenolics which lack the durability of FR4 but are much less expensive.

You will know you are working with this type of PCB when you solder to it - they have a very distictive bad smell. These types of substrates are also typically found in low-end consumer electronics. Phenolics have a low thermal decomposition temperature which causes them to delaminate, smoke and char when the soldering iron is held too long on the board. The next layer is a thin copper foil, which is laminated to the board with heat and adhesive. On common, double sided PCBs, copper is applied to both sides of the substrate.

PCB Basics

In lower cost electronic gadgets the PCB may have copper on only one side. When we refer to a double sided or 2-layer board we are referring to the number of copper layers 2 in our lasagna. This can be as few as 1 layer or as many as 16 layers or more. PCB with copper exposed, no solder mask or silkscreen. The copper thickness can vary and is specified by weight, in ounces per square foot. The vast majority of PCBs have 1 ounce of copper per square foot but some PCBs that handle very high power may use 2 or 3 ounce copper.

Each ounce per square translates to about 35 micrometers or 1. The layer on top of the copper foil is called the soldermask layer. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers. In the example below, the green solder mask is applied to the majority of the PCB, covering up the small traces but leaving the silver rings and SMD pads exposed so they can be soldered to.

Soldermask is most commonly green in color but nearly any color is possible. The white silkscreen layer is applied on top of the soldermask layer. The silkscreen adds letters, numbers, and symbols to the PCB that allow for easier assembly and indicators for humans to better understand the board. We often use silkscreen labels to indicate what the function of each pin or LED.

Silkscreen is most commonly white but any ink color can be used. Black, gray, red, and even yellow silkscreen colors are widely available; it is, however, uncommon to see more than one color on a single board.

Now that you've got an idea of what a PCB structure is, let's define some terms that you may hear when dealing with PCBs:. Not so accurate, but functional drill hits. Abe does a quick demonstration of how to line up a paste stencil and apply solder paste.

It's pretty awesome. Various portions of the PCB that have no traces but has a ground pour instead. The legs of the resistor go through the holes. The popular pogo pin with pointed tip.

We use tons of these on our test beds. Complex slots cut into the ProtoSnap - Pro Mini. There are also many mouse bites shown. Solder paste on a PCB shortly before the components are placed. Solder mask covers up the signal traces but leaves the pads to solder to. On the left, a solder pad with two small traces thermals connecting the pin to the ground plane.

On the right, a via with no thermals connecting it completely to the ground plane. A larger, thicker trace connects to the 5V power pin. Front and back of the same PCB showing a tented via.

This via brings the signal from the front side of the PCB, through the middle of the board, to the back side. How do you go about designing your own PCB?

The ins and outs of PCB design are way too in depth to get into here, but if you really want to get started, here are some pointers:. Finally, a few words on the utility of designing your own circuit boards.
