Applications of Low Volume PCB Assembly


● Prototype PCB assembly is usually used for sampling, testing, and design improvement

● Small batch PCB assembly is often ordered for scientific research by institutes

● Business makers often order low volume PCB assembly for business tries

● Hobbyists may also order low volume PCB assembly to bring designs into reality

● Companies may buy low volume PCB assembly for small-scale marketing

● Ensuring bulky PCBA order quality because low volume PCB assembly has the same quality as bulky PCBA

To understand where the cost of small batch PCB assembly is high, we need to decompose the entire link of contracting labor and materials. PCBA is a PCB assembly, including circuit board light board, component welding, SMT and DIP plug-in post-soldering. For the most part, the price of light boards on the market is more favorable for small batches, and the prices of components are basically open and transparent in major shopping malls, which can be compared for reference.

Small Batch PCB Assembly Cost


Small batch PCB assembly costs include labor costs, technology costs, turnaround time, parts packaging, and the number of PCBs required. Most Small batch PCB assembly units cost between $10 and $50, depending on the number of PCB assemblies. The main costs of small batch PCB assembly are as follows:

Prototype fee for smt chip processing

Small batch PCB assembly and SMT processing will vary in price depending on the number of points and packages. Large quantity and high price are the industry consensus. The larger the component package size, the easier it is to mount, and the corresponding poor quality will be reduced. Therefore, there is more room for communication in terms of price.

Welder hours after DIP plug-in

The plug-in material link involves special-shaped parts and material molding, and this link requires a lot of manual participation. Because there is no production capacity reference of machinery and equipment, this link is the most difficult link to control the cost of small batch PCB assembly. At the same time, the current labor cost remains high, and the cost of this process is generally high.

Small batch PCB assembly testing fee

The test fee for small batch PCB assembly includes test fixtures, test equipment, test man-hours, etc., and the test of communication equipment also needs the assistance of optical fiber, ICT and other test equipment, and the corresponding labor and equipment loss need to be taken into account, but will not very high, some low-volume PCB assembly companies even test for free.

Small batch PCB assembly auxiliary materials fee

Solder paste, solder bar, flux, UV glue, oven fixture, the quality of solder paste and solder bar are the most important auxiliary materials in the entire small batch PCB assembly and processing link. In the same soldering area, the price of imported solder paste will be much higher, but the difference in the quality of welding is very obvious.

How to Select Small batch PCB assembly Components

In small batch PCB assembly, on the premise of meeting the functional requirements of the circuit, components with high sensitive voltage threshold should be used as much as possible. Because the electrostatic and discharge sensitivity of a circuit board depends on the components with the lowest sensitive voltage threshold in the circuit board. Reasonable selection of components can effectively improve the success rate of small batch PCB assembly. 

Small Batch PCB Assembly Test Frame

PCBA test stand is widely used in the whole process of small batch PCB assembly and manufacturing. It is mainly used to test small batch PCB assembly boards after SMT patch and DIP plug-in. Among them, the ICT test is the main one, that is, through test points to test the electrical continuity of the circuit board to determine whether the entire PCB board is successfully welded. The PCBA test stand is the main tool used to assist in completing this test.

The quality of the PCBA test stand is related to the efficiency and pass-through rate of ICT testing. Due to its long-term frequent operation, there are high requirements for its production quality, which requires sufficient attention from small batch PCB assembly manufacturers.

Small Batch PCB Assembly Processing

1. In the process of small batch PCB assembly and processing, solder paste is required. For the newly purchased solder paste, if it is not used immediately, it must be stored in an environment of 5-10 degrees. In order not to affect the use of solder paste, it must not be placed in a sub-zero environment.

2. During the small batch PCB assembly process, the placement machine equipment must be checked frequently. If the device ages or some parts are damaged, the device must be repaired or replaced with a new one in order to ensure that the patch does not bend. Only in this way can the production cost be reduced and the production efficiency be improved.

3. During the small batch PCB assembly process, if you want to ensure the quality of PCB board welding, you must always pay attention to whether the setting of the reflow soldering process parameters is very reasonable. If there is a problem with the parameter setting, the quality of PCB board welding cannot be guaranteed. So usually, the furnace temperature must be tested twice a day, at least once. Only by continuously improving the temperature curve and setting the temperature curve of soldered products can the quality of small batch PCB assembly and processing products be guaranteed.

What environment is required for small batch PCB assembly

The processing technology of small batch PCB assembly has certain requirements on the workshop's power supply, ventilation capacity, temperature, humidity, air cleanliness, anti-static, and production personnel's wearing accessories. And the workshop environment tends to be more clean and tidy, with the purpose of reducing the health hazards to workers such as oil and dust. At the same time, environmental protection and greening are the pursuit and goal of modern development, because the environment of environmental protection and greening can reduce or control the generation of pollution sources. It can be seen that the material particles are relatively large, which mainly affects the visibility in the workshop, which affects the operation of workers in the workshop and the supervision of managers.

What is a small batch PCB assembly?

"Small batch PCB assembly" refers to a value with an area between 5-15 square meters. The specific quantity is based on actual conditions. Some manufacturers can provide a minimum of 1 pcb assembly service. In actual production orders, not all customers need tens of thousands of PCB assembly products. The testing of a small batch pcb assembly is an important step in the production process. Generally, small batch PCB assemblies are used to test and verify whether the project and design of a PCB are qualified. The delivery time for small batch pcb assemblies is approximately 1-5 days, while the delivery time for one-stop PCB assembly (including material procurement, SMT mounting, DIP plug-in, and PCBA testing) is approximately 10-15 days, depending on the data.

What are the advantages of a small batch PCB assembly?

As PCB circuit boards become an indispensable part of equipment, PCB proofing is one of the key factors in confirming the production of small batch PCB assemblies.
