Fast turnover PCB manufacturers typically state in their technical manuals and websites which types of printed circuit boards can be produced quickly. Some manufacturers only focus on standard FR-4 PCBs, but some manufacturers can also produce all types of PCBs, such as soft or hard flex or rigid boards, including high-density interconnect (HDI), depending on the available machines and tool types. Rapid manufacturing has a wide range of applicability, depending on the capabilities and service types of rapid manufacturing PCB manufacturers. The following are the various stages of products that can be applied for rapid manufacturing.

Rapid production of PCBs is an effective method for identifying and reducing design risks, especially in situations where product development time sensitivity is high. Due to the fact that the prototype is only produced in small batches, rapid production is a wise choice as it can obtain results in advance and provide sufficient space for further evaluation and improvement.

During the transition to production operation, a slightly higher quantity than the prototype batch will be run to simulate the performance of the printed circuit board. Some issues cannot be captured in small samples, so larger and more reasonable statistical sample sizes will be generated to understand whether the final design is indeed manufacturable. At this point, another batch of rapidly converted PCB boards may be needed for pre production testing.

Fast delivery of PCBs is also suitable for production operations, where early delivery is crucial. If the initial stages such as prototype design and pre production run are successfully passed, mass production will be smoother.

Let's be pragmatic, risks exist at every stage. There is no perfect design and production, especially in the initial stage. Being able to predict which factors will affect turnover time will help you understand the options to take. This will help to obtain the best fast turnover PCB without any errors.

The process capability of PCB manufacturers is crucial in the rapid production of PCBs. Manufacturers with rich experience and excellent rapid production capabilities can quickly produce PCBs. PCB manufacturers need to equip themselves with appropriate types of equipment and personnel to quickly complete all work from engineering to manufacturing and testing.

If the fast turnover PCB manufacturing company provides outdated and slow equipment, the compressed schedule will be difficult to meet. Each machine has different capabilities and units per hour (UPH). High speed machines that can meet customized PCB design have higher advantages in fast turnover manufacturing. Some suppliers, especially experienced companies, can provide flexibility in machine backup and simultaneous operation. For example, a company with multiple drilling machines will offer higher production capacity and provide alternative solutions in case of machine failure. Some Chinese fast turnover PCB manufacturers are using the most advanced equipment.

The procurement time of materials will significantly affect the delivery time of fast PCB manufacturing. We have inventory of the most commonly used materials, but some special materials may take several weeks to purchase.

Design engineers will check the availability of materials before designing PCB for rapid turnover. The selected materials play a crucial role in quickly completing the product. Suppliers must ensure material availability, as production cannot begin if materials are restricted. A good procurement strategy is to plan alternative materials and suppliers to cope with unavoidable shortages.

Undoubtedly, printed circuit boards with complex through-hole structures will have longer delivery times due to additional and complex drilling processes. More stacking or layers also mean longer lamination cycles, thereby affecting the overall project schedule. In short, PCB design can greatly affect the manufacturing and assembly time of printed circuit boards. Therefore, fast turnover PCB companies should work closely with designers to optimize PCB design.

The manufacturing complexity of circuit boards is also important. For example, higher-level HDI boards require longer delivery times, while simple double-layer PCBs can be produced quickly. With the development of equipment and technology, fast turnover PCB manufacturers are able to supply increasingly complex types of circuit boards.

Engineering configuration is usually necessary throughout the entire manufacturing process, especially during setup and inspection. This is one of the reasons why engineering expertise is extremely important. If a fast turnover PCB company does not have sufficient resources and good engineering judgment, some decisions in the manufacturing process may not be provided in a timely manner, which may affect the PCB fast turnover schedule.

Special process requirements can also affect the delivery cycle of fast PCB boards. For example, countersunk holes, peelable masks, hard gold coatings, VIPPO through-hole plugs, etc.

Quality control and planning may also affect the production time for rapid PCB production. IPC Level 3 standard PCBs require longer time for quality inspection.

For fast turnover PCB services, every day is important. You may be concerned that Chinese fast turnover PCB suppliers may not be able to meet your requirements. But it is very easy to transport goods from China to other countries in the world. Air freight usually takes one week, while sea freight takes 3-4 weeks. But the delivery may take 2-3 working days.

To obtain a finished product, a fast printed circuit board needs to go through the following steps.

Firstly, computer-aided design (CAD) must be used to develop PCB designs. Design is the blueprint for the subsequent process. The design phase is the stage of defining the circuit layout and schematic. Different circuit components are filled into each PCB layer.

All relevant details of the PCB must be specified in the design document. The format type submitted to fast PCB manufacturers is called "Gerber file", which is a known board layer format in the industry. The Gerber file indicates what the device should follow and where it should go. The aperture library and drilling files are sent separately, and they determine the hole size to be referenced.

The output of any PCB design is preliminary, which lists the substrates, copper foils, and other materials required to build a printed circuit board. The PCB file format is usually Gerber 274 format, which is widely accepted by PCB manufacturers. In the Gerber file, PCB materials are clearly written, such as FR-4, aluminum, ceramic, etc PTFE、 Polyimide, etc.

The patterning process is the use of photolithography and other techniques to transfer designs onto copper plates. Photolithography technology utilizes photoresist, which is a photosensitive material that can dissolve or not dissolve under light. This process can print the required copper patterns onto the board.

The circuit board with patterns undergoes etching process to remove unwanted copper foil, leaving the expected traces and patterns on the PCB. After the corrosion etching process, use a stripping solution for cleaning.

Next, specialized equipment will be used to drill holes in each layer, which can be accomplished through mechanical or laser methods. PCBs with higher density and smaller holes usually require longer processing time, resulting in higher costs.

Due to the fact that holes or vias serve as connections between layers, they are plated with copper to form conductive paths between the layers of the PCB. Copper plating also has another function, which is to increase the copper thickness of the copper wire.

The solder mask layer is printed on the top and bottom of the PCB to protect the copper area outside the solder pads.

Screen printing, also known as component marking, is a component marking printed on the surface of a PCB to clarify the position of components, which is very useful for the installation, repair, and maintenance of components. PCB assembly process

The exposed copper pads on the PCB can also be surface treated with various chemicals to protect them from changes in environmental temperature and humidity. Due to the easy oxidation of copper, surface treatment or finishing is an extremely important step. The most commonly used PCB surface treatments are HAL, ENIG, and OSP.

The main purpose is to manufacture circuit boards that meet design and functional requirements; Therefore, PCBs should undergo visual inspection processes such as automatic optical inspection. For fast PCB manufacturing, these are still necessary steps to understand defects and issues as early as possible.

The PCB still needs to undergo testing to check for circuit issues such as short circuits and open circuits. For small-scale manufacturing and prototype design, a flying pin tester can be used to access the contact pads. For large-scale production, online testing is a better choice because the operation time is faster.

Now that you have learned some basic knowledge of fast PCB manufacturing, we will discuss the different factors to consider when choosing a suitable fast supplier.

Time is the golden requirement for achieving rapid turnover of PCB projects. A suitable supplier should have shorter delivery times and develop detailed strategies to follow the promised schedule. In order to meet the urgency of construction, every process should be efficient, as any delays and non-standard work in the process will slow down the entire project. Potential delays should have corresponding mitigation plans in place to address the issue immediately. Most rapid turnover manufacturing supplier websites list typical turnover times to guide customers in making decisions.

Suppliers should have advanced machines with sufficient functionality and capability to support fast PCB type processing. Manual work only interferes with the process because it is slow, prone to errors, and prone to error handling. With decades of development in PCB manufacturing, China's rapid PCB manufacturing technology is at the forefront of the world.

Suitable suppliers should also be able to provide lower costs. Like any business, this is a factor that determines the success or failure of a transaction. Ensure understanding of the scope, terms, and conditions specified in the submitted quotation to prevent communication barriers and further modifications. Suitable suppliers will also provide advice on how to maintain flexibility in payment and how to reduce costs. Chinese fast turnover PCB manufacturers can produce high-quality circuit boards in a short period of time.

With suitable suppliers, quality should also exist in every process and every field. This means that fast turnover PCB manufacturing companies follow a quality management system, which includes a series of rules and standards that need to be followed. Due to the high technological content of printed circuit boards, various certification bodies such as UL (Underwriters Laboratories) and IPC have outlined requirements and guidelines for designing and manufacturing high-quality, safe, and reliable electronic products.

Good customer service is also crucial to ensure the smooth progress of design, pre production, and mass production. Some rapid manufacturing suppliers only respond at the beginning of the project, but this is not the case. Throughout the entire lifecycle of the product, suitable suppliers should still be involved and committed to responding quickly and promptly to technical and non-technical inquiries.
