The Top 3 Components of a Turnkey PCB Assembly

Pcb fabrication

The cell phone that you use on a daily basis has a very complex design process. Even the TV that you turn on after a long work day has many detailed inner workings. The absolute base for these advanced electronic devices comes from the turnkey PCB assembly. In fact, the turnkey PCB assembly is the basis for many of the complex and advanced technological devices that you use every day. A basic PCB fabrication consists of a few generic parts that are then built upon to completely customize the turnkey PCB.

Temperature control
Because most electronics work on electrical wirings, the temperature needs to be carefully controlled until the device is completely designed. Your cell phone and TV have cooling properties that are able to identify when the product is close to overheating, and the cooling property kicks in. However, before these designs are completed, there is a risk of overheating. For this reason, temperature curves are necessary in the printed circuit board assembly process.

Temperature curve plays a critical role in determining soldering quality. Prior to 160 degrees Celsius, temperature rising rate should be controlled at 1 to 2 Celsius per second. If temperature rises too quickly, on one hand, components and PCB tend to suffer heat too quickly, which tends to destroy components, leading to deformation of PCB. The entire PCB and all of the design work that was thus completed on it will have to be redone.

Time control
A turnkey PCB assembly can cut down on design time, because it already provides designers with a starting electronic base. It is important to keep time constraints in mind, as there are many different electronic options to test. If you were to spend too much time on one aspect of the turnkey PCB assembly, you are likely to not get very far in the design process. The advent of machine assembly for any size orders means that shops can assembly PCBs in a fraction of the time it would normally take for hand placement. In fact, some PCB assemblers have a standard turn time of 5 days or less, which is 75% faster than the industry average.

This significant increase in time could potentially drastically change the design process. We could realistically see much quicker of turnaround times on both design improvements and entirely new designs. We would also likely see more turnkey PCB assembly bases with increased designs for advance technological designs. PCB manufacturing companies could also receive an increase in profits, as they are able to turnaround new designs much quicker.

Multiple layered boards
Turnkey PCB assembly boards come in a variety of layered boards. The specific amount of boards that are needed will depend entirely on the type of project. The most common multilayer boards are 4 layers, 6 layers, 8 layers, and 10 layers. However, the total number of layers that can be manufactured can exceed over 42 layers. These types of boards are used in extremely complex electronic circuits, such as your cell phone and your smart TV. We are likely to see even more layers on even more advanced and complex electronic circuits as designers and scientists continue to improve upon our smart phones and mobile internet devices.

The industry of electronics and mobile devices is extremely detailed and complex. Although the basis for most designs is the turnkey PCB assembly, it is the designs that are built upon this that really matter for productivity. It is the differences among these turnkey PCBs that really make the differences between different electronic and mobile devices. The PCB manufacturing industry continues to make improvements, these improvements have the ability to create extremely layered boards, as well as a significant increase in turnaround manufacturing times.
