A quick turn PCB compresses the entire production timeline—from design, fabrication, and assembly to testing—into an accelerated schedule, typically ranging from 12 hours to 10 days, depending on complexity.
Simply, a two-layer PCB, its manufacturing costs can be kept at a minimum and delivered on a very quick timeline
As complexity increase, PCB fabrication and production will be longer in turn. Keeping these factors in mind is critical to right decision when you plan to have a quick turn PCB requirement for your project.
There are some benefits why a quickturn PCB service is preferred.

Quick turn PCB manufacturing and assembly lead times are driven by critical variables:
*Pro Tip: Simplify designs and use common materials to achieve 24-48hr turnarounds for standard circuit boards.
| PCB Type | Layers | Fab without assembly (days) | Fab and assmelby (days) |
| Standard FR4 | 1-6 | 1-3 | 2-4 |
| Standard FR4 | 8-12 | 3-5 | 5-6 |
| Rigid-flex | 1-12 | 6-8 | 7-9 |
| Flex | 1-10 | 3-6 | 5-7 |
Today, there are thousands of printed circuit board manufacturers in the US, Europe and Asia, so it is very easy to have your PCB manufactured at any time per your demand. But there are some key factors on PCB manufacturing that you simply need to know before you begin working on your PCB design. These factors can save your time and cost once considered it into your design.
Follow DFM guidelines to get top quality circuit boards. Check the base material and components availability before using it in your PCB desing and work out the best layout matches for a compact design. Provide specific test requirements and list a clear test equipment beforehand is key for a rapid prototypes.
An HDI printed circuit board has different types of via strucutres will need multi-lamination cycles. Every cycle you laminate a HDI board, it is like making another multilayer board. It will incease the cost of the PCB. The lead time for advanced technology quickturn boards with multiple lamination process will be longer than that of standard technology printed circuit boards.
The exact time required for a lamination cycle determined by the number of layers in PCB stack up, and the base material selected. Typcially, each extra added lamination cycle will increased another 3-5 days for the production process. This includes the time taken for any type of hole drilliing, palting, or filling. Eexcept the time take for lamination, another necessary consideration that one additional day needed the out layers process.
For example, the stack up in above picture presents an HDI PCB desinged with stacked via and micro vias. Such an HDI PCB board would have a 2+N+2 stack up, and need a total of 3 lamination cycles, the lead time of such type of board usually would be 10-12 days.

Most time, the designer have to design the via holes in surface mounting PAD, so as to saving the spacing and reduce the PCB overall size, lower PCB layers as well. Or this process may be used to keep heat dissipation from under the component. The manufacturing technology of Via in PAD design become very common now and no challenge to most of PCB manufacturers, but be ware of that they can add one day at least to manufacturing cycle time.
A specific PCB fab drawing present important manufacturing information like some critical mechanical dimensions, PCB layers, board thickness, base material, copper thickness, specific layer stack-up, drill chart, surface finishing, the color of solder mask and silkscreen, specific critical tolerance such as press fit holes, controlled impedance details, IPC class 2 or 3, the details of other special requirement such as countersink-holes.
PCB layout engineer need to thoroughly know the PCB manufacturer’s capabilities to bridge the gap between design and design and DFM. For example, the minimum track width/spacing, the spacing between hole and track should be accommodated in the manufacturing process to avoid any re-design time delays.
If no special dielectric thickness requirement, the stack-up must match manufacturer’s standard stack up as possible, these will mean you will get availability of base materials, and get cost down and shorten the lead time accordingly. Once you have to consider a special stack up from impedance purpose, you need to cooperate with the engineer of your supplier to generate a production stack up that they have available materials in stock to avoid any impacts on the lead time once some prepgrege or core is out of stock. Of course, you need to specifically list your impedance requirement(layers, impedance type, impedance value, etc). After all, the less mismatched information, the more possibility to avoid delays.
Surface finishing is another time consuming production process. ENIG (Electroless nickel immersion gold) and HAL lead free are the most commonly used surface coatings. Normally, HAL LF takes around 15-30 minutes but ENIG takes 90-130 minutes. Alerts that some PCB manufactures in China do not have ENIG production process at house and need to sub-contract it to outsources with which takes 1 day more on this process.
If your circuit board have edge contacts on and need to be hard gold plated, plus ENIG surface finishing, that means you need multiple surface finishing ENIG + Hard gold plating, then you need to consider twice time of the plating process. As each finishing must be done separately and have to go through the complete process twice.
A complete assembly drawing will have a right instruction to your PCB assembly manufacturer that how to assembly your board properly. Normally, it includes the specific information such as: BOM list, top and bottom silkscreen, identification label if any, other assembly-specific notes. The assembly drawing along with fab notes will be the good reference to the inspection of the bare printed circuit board and assembly. The following pointes would avoid delays during PCB assembly process:
