Circuit boards
Designing a new device often requires very advanced work. Experienced designers perfectly understand the phenomenon of prototypes, i.e. a prototype of a device for the right one. This is what we start every project with. We can decide to design a new device, but you have to be aware of the difficult, hard and advanced work. For some people, high costs are also an obstacle, which are associated with it. The alternative is a universal PCB, with which we can check and test the electronics. Universal boards differ in construction and size. Its choice must not be accidental, but should depend on the electronic elements used in this particular circuit. We will choose another board for a simple circuit, and another for a more complicated one. In our offer there are many types of universal boards, which we recommend for prototyping for beginner electronics and robotics, as well as for the more experienced ones.

Electronic printed circuit board - What can prototype boards be used for?
Electronic board - The most common soldering pad spacing used on universal boards is 100 mils , which corresponds to exactly 2.54 mm . This is the spacing between the centers of the mounting holes that most often have electronic components in through-hole housings (THT) - resistors, capacitors, goldpin connectors, integrated circuits in SIP and DIP housings, many displays, transistors, LEDs, etc. The soldering fields on the universal board are large, so no soldering, regardless of the technique used, should not pose any problems even for electronics beginners.
Some boards are equipped with SMD fields with rasters corresponding to the most popular housings of surface-mount components. In this category you will also find PCB boards dedicated to building Raspberry Pi Hat type shields. A unique, round PA07 prototype board was created for unique projects! PCB production, thanks to stable production parameters, will be characterized by repeatability, precision and high quality.
Construction of a universal printed circuit board
Two types of paths are most often used, corresponding to the arrangement of the plates in the breadboards: short paths , covering several soldering pads, and long ones , running along the edge of the board, containing several to several dozen soldering pads. The first, shorter ones, are used to make connections (nodes) between individual pins of electronic system elements.
We encourage you to check out the entire prototype boards section, where you can find, among others: SMD-DIP adapters, breadboard accessories , breadboards and many others.
Printed circuit boards - additional information
Longer paths are perfect for use as power rails - ground and supply voltage. In the case of larger universal boards, several rails are available - they can be connected to each other to increase the number of pins in a given network (e.g. ground) or used separately for several different supply voltages (e.g. symmetrical +/-5V for analog circuits). Assembling electronic components on a PCB is the fastest way, for example, to design electronic devices. Universal plates are covered with a layer of copper. Additionally, the presence of insulating material eliminates the risk of short circuit. In addition, printed circuits are susceptible to mechanical processing.
What can and cannot be built on a printed circuit board?
Simply put, printed circuit boards are suitable for soldering all typical electronic systems operating at low voltages and low frequencies.
Please remember that due to the relatively small spacing between the traces, universal PCBs are not suitable for working with voltages of several dozen or more volts, while the width of the traces limits the ability to carry higher currents. The production process includes chemical treatment.
In addition, the PCB is covered with a layer of copper. If you have additional questions about PCBs, please contact us by e-mail, via the contact form or by phone.
Universal tiles - FAQ
We recommend choosing Hot Air soldering irons and soldering stations . With their help, we will create truly lasting connections. They will also solve the problems of traditional soldering irons, such as the difficulty of attaching small elements - resistors or transistors . At the beginning of your workshop journey, it is also worth purchasing: a cheap board for learning SMD soldering.
First, make a clear design. The life of each of them begins with a prototype, and choosing a prototype board with holes for through-hole elements is an idea to reduce costs and speed up the implementation time. We thought about it - the Adafruit LED prototype board is waiting for you in Botland in a multi-pack of 10 pieces.
PCB is a printed circuit board - the abbreviation comes from the English Printed Circuit Board . What does it mean? Laminated sandwich structure consisting of conductive and insulating layers. I'm sure each of you has seen such a perforated piece of fabric somewhere. PCBs are covered with a layer of copper and trace patterns are applied.
PCB cleaning is important. They should be washed because flux residues, dust or greasy fingerprints settle on the surface. These contaminants usually become the source of problems such as corrosion, short circuits or the inability to apply a protective coating.
The PCB can be cleaned dry or wet. The most popular cleaning methods are the use of sand, soda, dry ice, solidified carbon dioxide, ultrasound and commercially available cleaning agents. Ultrasonic cleaners are the best way to clean PCBs, which you will find in the Botland store.
