Characteristics Of Pcbnet Printed Circuit Boards

We follow the IPC standard of printed circuit boards which is congruent with the requirements of the electronics industry. The company makes sure that we pass the assembly, design and standards requirements of the industry. Our printed circuit boards are characterized either as through hole technology or surface mount technology.

PCBNet Through-Hole Technology

Pcb-fabricationBy piecing together electronic components using leads that are inserted into holes we are able to produce some of the industry’s most durable printed circuit boards. The way we do it is by inserting leads through the holes on one side of the circuit board and soldering copper traces on the other side. We produce both single sided and double sided circuit boards. Our single sided boards have a component side that is unplated. Our double-sided boards are very compact with all electronic components soldered on the two sides of the board.

When it comes to our production of diodes, resistors, and capacitors all use horizontal installation using two axial leads on through-hole parts.

The process goes something like this:

1. Leads are bent in the same direction 90 degrees.
2. To improve mechanical strength, bend the leads at the back of the board in opposite directions.
3. Insert the part and solder the leads on the board.
4. Ends should be trimmed off after soldering.

When soldering, we either do it manually or with the use of a wave soldering machine. Since the introduction of through-hole printed circuit board technology, the industry has never looked back again towards using point to point construction. Point to point construction was the very first printed circuit board assembly technique. Because of the popularity of through-hole technology, it is reasonable to say much of the computers and electronic devices produced since the 1950s will have printed circuit boards that contain components made from through-hole technology.

Our through-hole technology requires numerous holes to be drilled onto each board in an organized and accurate way. The downside is it increases manufacturing costs because it reduces the routing area for each circuit board. This is especially true for multi-layer circuit boards that are assembled one on top of the other. With through-hole technology it is necessary to drill the same hole on all the boards. For some of our clients requirements PCBs manufactured using through-hole technology is the just the way to go. That is if cost is not an issue.

For most client however, cost is a concern and our through-hole technology PCBs are just way too expensive for them. This is where PCBNet’s surface mounting technology comes in, our cost efficient printed circuit board design that delivers both on quality and affordable cost.

PCBNet Surface-Mount Technology

As the name indicates our printed circuit boards produced using surface mount technology have components that have been designed with end caps or metal tabs attached. Because of this design innovation on individual components, we are able to solder onto the surface of each circuit board all components. No need to drill in holes the way through-hole technology does. The result is an ability to maximize the space on each board. With surface mounting technology we can pack in more components onto the smallest PCB, something through-hole technology cannot deliver.

It is more cost efficient because of the following reasons:

1. We can produce using automation.
2. We use smaller PCBs that pack in a dense assembly of components.
3. We reduce cost of labor.
4. We increase rates of production.
5. Less expensive material cost for purchase of semiconductors, signal switch diodes, and other individual components.
Printed circuit boards manufactured with surface mount technology are sure to be inexpensive and are a great option if you are looking to order a large volume of PCBs.


In terms of the circuit properties of our printed circuit boards, below is a detailed listing for your information:

pcb_fabrication1. Every individual trace contained in the PCB has a narrow and flat foil of copper that is retained after the etching process.
2. The resistance on each trace is kept low so that the current from the conductor can pass through each trace.
3. All ground and power traces on our circuit boards are wide compared to signal traces.
4. In our multi-layer boards there will always be one complete layer covered with solid copper to act as a ground plane. It is supposed to shield and power the return.
5. In our microwave circuits, microstrip and stripline with very controlled dimensions for consistent impedance are placed on transmission lines.
6. In terms of fast switching circuits and radio-frequency, the capacitance and the inductance which are printed on the circuit board can sometimes be insignificant. But we keep them there anyways as additional circuit elements that prevent the addition of new discrete components.

At PCBNet, we make sure all quality of production is kept to the highest standard while delivering the specific requirements dictated by individual clients.
