1.Description:

With Sprint-Layout you can design your PCB’s quick and easy. There is no unnecessary “ballast” which makes it difficult to keep the overview or which makes the usage almost impossible. Because of the logical and understandable structure of Sprint-Layout the usage is very easy to learn. So finally, you can concentrate to the essential thing: Designing and optimizing your PCB-layouts.With the free viewer-software for Sprint-Layout, it is possible for everybody to view or print your layouts.

How To Better Identify A Cold Solder Joint

Abstract

Soldering is the most basic skill required to assemble any electronic circuit. Soldering is a chemical process in which solder (a mixture of tin and lead) is heated to flow over the two joined surfaces: i.e., the PCB and the component pin. Cold Solder Joint takes some practice and theoretical background to make a perfect joint and with speed. The soldering compound is hard and elastic at room temperatures but it melts rapidly beyond 160°C temperature. The soldering iron or soldering station is the tool that heats the solder to flow.  

A soldering iron is generally a single tip of hot metallic needle fixed in the heating element and is not a temperature controlled tool. The soldering station, although is costly, is a temperature controlled tool that maintains the temperature of soldering tip within limits of defined temperature settings. More the temperature is controlled and maintained and the perfect solder compound the more perfect is the soldering joint.

The Better Introduction Layer Stackup It's Here

Abstract

The proper positioning of the type of layer is called the layer stackup. The PCBs generally categorized as the single layer, double layer and multilayer PCBs that actually describe the number of conductive layers or copper layers in a PCB. The PCBs with more than two layers such as 4, 6 and 8 etc., are known as the multilayer. In a multilayer, the top and bottom layer are called the outer layers and the layers within these two are called inner layers. The layer count roughly defines the complexity of designed circuit, total number of pins and density of signals. A simple PCB is an insulator sheet of FR-4 material with the copper sheet on at least one side. As the circuits are becoming more complex, dense SMD chip packages, operating at high frequencies and multiple power supply rails the PCB design and fabrication is becoming more and more complex. The circuits are laid out on two and higher layer count PCBs. The multilayer PCBs are more costly compared to double layer PCBs.

PCBs Manufacturing - The Most Detailed Introduction(Helpful)

Abstract

PCBs Manufacturing standard stands for Institute for Printed Circuits, currently known as Association Connecting Electronics Industries It was found in 1975 for setting the standards for bare PCBs and finished PCB assemblies.

The IPC classes for PCBs manufacturing are known as IPC Class-I, Class-II, Class-III and Class-III/A. It is obvious that class-I is the basic of PCB manufacturing quality.

As well as the Class-III/A the strictest. All three classes belong to the IPC-6011 standard. The major difference between classes is their level of qualification.

Single-Sided And Double-Sided PCB - What You should know(latest)?

Abstract

Single-sided and Double-sided PCB is a matter of routing and design convenience at the cost of a more complicated manufacturing process. The following is a detailed introduction of these two kinds of PCB.

Content 1. Single-sided PCB 2. Double-sided PCB

1.Single-Sided PCB

Single-sided PCB is the basic one,the spare parts are concentrated in one side, and the circuit is concentrated on the other.Because the wires only appear on the one side of themso we called Single-sided PCB. Because the single-sided PCB has many strict restrictions on the design circuit (because only one side, the wiring cannot cross and must move around the individual path), so it only used on earlier circuits.

How To Use Trace Width Calculator(Fundamentals)

Abstract

Calculation of appropriate trace width calculator sizes for current carrying is an important requirement of circuit boarddevelopment. Common materials used for PCB tracks layout are copper and aluminum. It can offer a small resistance when current flows through them.

The resistance of a conductor at room temperature depends over three factors namely the conductivity of the material, effective length.Also the cross-sectional area of the conductor.

How To Tell If My Computer Has Bluetooth

Abstract

Bluetooth technology allows us to connect different devices wirelessly, in order to be able to send content from one computer to another and share different material, without the need to use cables in between, and it is precisely for this reason that in recent years there has been become an increasingly used platform.

That is also why currently almost all portable devices, and even many laptops and desktops, have the factory with this technology, and the truth is that users are only advised to purchase equipment that has Blue-tooth.

How To Make A Custom PCB Printing

by @sunshine - May 08, 2018
Abstract

Designing custom PCB printing is easy. All that you need are materials, tools and PCB boards. You also need a mini drill, Ferric Chloride and a container. Other tools that you need is a container, a bottle of thinner and plastic tweezer. Once the materials and the tools have been collected, it will take you 30-45 minutes to make a custom PCB printing circuit. The PCB can then be used to connect electronic components using copper sheets. Alternatively, you can have the components connected to conductive materials such as copper.
