A PCB fabrication starts with the need to create a specific printed circuit board functionality. This need comes from you, our customer. When this purpose is established, designing the board and its manufacturing process becomes easier. However, before a design becomes feasible for production, our engineers perform many revisions and consider many factors.
The Budget Factor
One of the driving force in the creation of good PCB is the cost of manufacturing. Most of the times, the cost also determines whether the PCB will fail or not. Why? In the manufacturing of printed circuit boards, the more layers you require the higher is the cost. The quality of the components, the type of the substrates, and the mounting technology add up to the cost of producing the printed circuit board.
Thus, when it comes to the design process, we take note all of these factors while maintaining good functionality of the PCB. The cost factor should not be the reason for sacrificing the overall quality of the board.
The Design Documentation
In the design process, the engineers prepare proper documentations to avoid misrepresentation and misinterpretation. These documents become the guidelines during manufacturing. Aside from serving as guidelines, these documents are evaluation tools when defects are discovered in the testing stage. A good practice of design documentation is recording the exact stage where the defects resurface. These defects are used to rectify the design. This practice prevents the next batch of the PCB in containing the defects discovered in the previous batch.
In PCB fabrication, our engineers prepare several documents essential in the manufacturing of the PCB. These are the bill of materials, detailed schematic, layout a profile, assembly drawings, Gerber files, file on component placement and dimensional sketches.
These documents provided by pcbnet, contain instructions on the PCB assembly, the components and raw materials used.
Proper management on all aspects of the fabrication and assembly contributes to the quality of the final product. In our company we make sure we follow all regulations and government requirements in our fabrication and assembly processes. These regulations include proper labeling and handling of chemicals. We require all of our personnel to use gloves that have anti-static properties. We also request them to avoid using lotions and other creams during assembly since the oils in these beauty products may affect the performance of the assembled PCB.
Before the assembly team enters the assembly area, they undergo a cleaning process to strip the body oils and beauty products they have used prior to the work hours. Alternatively, we make them wear anti-ESD clothes or jumpsuit.
The Testing Stage
This stage is important to detect whether the PCBs are functional. Before we proceed to the packaging of your orders, we repair any defects we find. Do not worry since these PCBs, despite being repaired, are still in excellent quality. In case, the PCBs are not in working condition, we replace them with new ones. After the testing stage, we remove the unnecessary materials in your PCBs. We remove moisture by baking the PCBs to a certain temperature and immediately forward the items to the packaging department.
The Packaging Materials
Delivery and transportation creates vibration and brings shock to the sensitive PCB. Thus, we mandate our assembly and fabrication team to never stack the PCB on top of the other PCBs. A good practice is to use a stacking cabinet if the items are not to be transported and delivered immediately. We also use bubble plastic and anti-static packaging to ensure that the PCBs are in good condition when the products reach your establishment. Aside from these, we place moisture indicator in the packaging as warning. You may also find a simple instruction on how to handle the PCBs upon receiving, how to report any defects and the necessary documents to return the product to us.
To put it simply, our PCB fabrication methods are excellent in quality. We perform the processes in accordance with the quality standards. In cases that the PCBs are not working once you receive them, you can return them to us. However, we require a complete description of the defects you found so we can change the design schematics. These changes will reflect on the next batch you order from us. In some cases, we may even give you discounts on the cost.
PCB fabrication requires good practices, good quality raw materials, and high quality process management to create excellent quality of PCBs. With our years of experience, we have mastered all of these.
