Quick Turn PCB Fabrication

In terms of product types, the global quick turn PCB fabrication industry is moving closer to high precision, high density and high reliability. The development of the electronic equipment industry. Quick turn PCB fabrication companies will further increase their investment in technology research and development, and the high-speed, high-frequency and high-heat applications of multilayer boards will continue to expand, and more sophisticated HDI boards and more advanced wafer-level packaging technologies will appear.

Development Trend of Quick Turn PCB Fabrication

China is the largest quick turn PCB fabrication country in the world, but its enterprise scale is smaller than traditional powers such as Japan and South Korea, and its industry concentration is relatively low. Looking forward to the future development trend of domestic quick turn PCB fabrication, the increase in industry concentration is the general trend.

Compared with regions with mature quick turn PCB fabrication industries such as Japan and South Korea, China has the advantages of lower labor costs, huge market potential, concentration of downstream industries, and land, water and electricity, resources and policies. China transfer.

Quick Turn PCB Fabrication Cost

Quick turn PCB fabrication is a necessary process before mass production of each electronic product, and there are many factors that affect the price of quick turn PCB fabrication

1. Flying probe test: Flying probe test is very important to the quality of quick turn PCB fabrication. Reputable quick turn PCB fabrication manufacturers usually perform flying probe test after the production is completed. Generally, circuit boards with a small number and simple information, some quick turn PCB fabrication manufacturers The flying probe test will be done for free, but if the data involved is very complicated and the quantity is large, the flying probe test will be charged.

2. Surface treatment: Surface treatment will be carried out on the substrate during quick turn PCB fabrication, and the cost of surface treatment of different circuit boards varies greatly. For example, the cost of immersion gold treatment is higher than that of ordinary HASL process. When the surface treatment fee is an important part of it. the

3. PCB ink: The cost of solder resist character ink in quick turn PCB fabrication is different according to the type of ink selected. When the company has special needs when making boards and the order quantity is very small, quick turn PCB fabrication manufacturers will waste more ink. If specified When a certain brand of ink is used, the quick turn PCB fabrication price will be higher than that of ordinary ink.

4. PCB board cost: PCB board cost is mainly related to the size of the PCB board. The larger the size of the PCB board, the more PCB base material will be consumed, and the PCB base material is the largest piece of raw material expenditure in quick turn PCB fabrication. The general price The calculation is based on the size multiplied by the fixed board fee coefficient.

In addition to the above four points, the number of quick turn PCB fabrication layers, process precision, copper thickness requirements, number of holes, and board thickness are also important factors that affect the quick turn PCB fabrication price. Secondly, if you need to expedite, you need to charge an extra fee Expedited fee.

Documentation Required for Quick Turn PCB Fabrication

There are many forms of quick turn PCB fabrication files. In order to meet the different needs of the market, quick turn PCB fabricationh manufacturers can generally open these different forms of files. So, what documents are needed for quick turn PCB fabrication?

It is usually necessary to provide PCB or GERBER files to the quick turn PCB fabrication manufacturer, and the provided files must include some board making instructions, such as: quantity, whether to make boards, number of layers, board materials (specific PP materials can be provided if there is mixed pressure), ink color , solder mask color, etc.:

Material: It is necessary to explain what material is used to produce PCB. Generally, FR4 is the most commonly used, and the main material is epoxy resin stripped fiber cloth board. For some special high-frequency materials such as Rogers, specify the specific model.

PCB Board layers: The number of PCB board layers has an impact on the price, so it is necessary to indicate how many layers of boards are made.

Solder mask color: The regular color is green, other colors need to be specified.

Silkscreen color: the color of the font and frame of the silkscreen on the PCB, the default selection is generally white.

Copper thickness: Generally, the thickness of copper is scientifically calculated according to the current of the quick turn PCB fabrication circuit. Generally, the thicker the better, but the cost will be higher, so a reasonable balance is required.

Whether the via hole is covered with solder mask: over solder mask is to insulate the via hole, otherwise the via hole is not insulated.

Surface coating: HASL or gold plating. HASL is divided into leaded and lead-free HASL.

Quantity: The quantity of quick turn PCB fabrication and whether to make boards should be clearly stated.

Sometimes customers also have requirements for specific parameters of materials, as long as special processes are involved, they must be provided.

Standards for Quick Turn PCB Fabrication

In electronics manufacturing, quick turn PCB fabrication standards fall into three categories: 1, 2, and 3. These categories reflect the quality level of each quick turn PCB fabrication type, from the lowest (Class 1 standard) to the highest (Class 3 standard). This classification system was developed and monitored by IPC according to the IPC-6011 standard. Perhaps the main difference between each level is the degree of inspection that electronic components must undergo and the quality standards they are subject to.

In the IPC-A-610C document, electronic products are divided into Level 1, Level 2, and Level 3. The higher the level, the stricter the quality inspection conditions.

Level 1 products: known as general-purpose electronic products. Includes consumer electronics, certain computers and their peripherals, and products whose primary use is functionality.

IPC secondary products, that is, special service electronic products, including communication equipment, complex industrial and commercial equipment, and high-performance, long-life measuring instruments. The IPC level 2 standard clearly states that this type of product should not fail under normal usage conditions.

The IPC level 3 products, that is, high-performance electronic products, include high-reliability, long-life military and civilian equipment that can continue to operate. Such products are absolutely not allowed to be interrupted during use, and at the same time, reliable startup and operation of the equipment must be ensured in harsh environments. Examples include medical lifesaving equipment and all military equipment systems.

Huihe Circuits is a quick turn PCB fabrication manufacturer. PCB products are used in consumer electronics, automotive electronics, communication equipment, industrial control equipment, 5G and other fields. They are strictly in accordance with IPC-level calibration standards. If you have any needs, please feel free to contact us!
