What Is Mass Volume PCB Assembly
Mass-volume PCB assembly refers to the number of DFM inspections and DFT inspections greater than or equal to 1000 pieces. High-volume production requirements for PCB assembly are usually made by customers and require multiple copies of standard or customized printed circuit boards to be installed.
What Advantages Can You Get From Mass Volume PCB Assembly Provider
Suppliers with large-scale manufacturing capabilities and well-equipped facilities can provide customers with various advantages, reduce the production time of PCB assembly, and ensure on-time delivery.
(1) Save time and cost
Manufacturers use automatic slicing machines in the production process, and workers are engaged in the same operation for a long time, which improves the proficiency of labor and can reduce the time for mass PCB assembly.
(2) Guaranteed PCB performance
All PCBs undergo strict automated optical inspection (AOI), online testing (ICT) and X-ray inspection. This can ensure that all assembled PCBs meet the quality requirements of the industry and meet the PCB assembly speed.
(3) Save total cost
Mass purchase of PCB assembly can save time and cost on the one hand, and production cost on the other hand.
Why do PCBs need to be tested after production?
PCB testing after PCB production allows the factory to find problems in time. For example, solder joint problems, pin problems, whether the component position is offset, whether there is a solder short circuit phenomenon in the PCBA, etc., and correct them in time.
The advantages of PCB post-production testing:
(1) Defect identification: The most important and basic function provided by PCB testing is defect identification. Testing allows the factory to discover the problem in time and make corrections in time.
(2) Reduce production costs: Finding problems in time when manufacturing PCB prototypes can reduce the cost and risk of mass production and reduce the rework rate.
(3) Improving delivery speed: The factory discovers problems in time during prototype production inspection, which can avoid this problem in the later production process, thereby reducing risks and increasing delivery speed.
What are the PCB assembly tests used by suppliers
With the advancement of science and technology and the development of production, electronic technology has become an indispensable part of our lives. In order to meet the needs of the market, mass-produced electronics has become the current mainstream. Compared with ordinary assembly technology, mass production assembly technology will definitely cause differences in the products produced. So what kinds of PCB assembly test methods do suppliers generally use to determine product functional problems?
(1) In-circuit tester (ICT): In-circuit tester, abbreviated as ICT, is an automatic online tester, which is a necessary PCBA production test equipment for modern electronics companies. ICT Test mainly detects the open circuit, short circuit and welding of all parts of the PCBA through the test probe contacting the test points of the PCB layout. It has a high fault location and a certain fault diagnosis function. ICT uses computer programming, so the test speed is extremely fast.
(2) AOI: AOI is based on optical principles to detect common defects encountered in welding production. AOI uses high-speed and high-precision visual processing technology to automatically detect various mounting errors and soldering defects on PCB boards. The PCB board ranges from fine-pitch high-density boards to low-density large-size boards, and can provide online inspection solutions. To improve production efficiency and welding quality. By using AOI as a tool to reduce defects, errors can be found and eliminated early in the assembly process to achieve good process control. The inspection is performed at the last step of the SMT process. This is the most popular choice for AOI, because all assembly errors can be found at this location.
(3) FCT: FCT tests to check its meaning. This strategy is implemented in the final stage of production to check whether all the functions of the PCB are operating according to the customer's specifications. Test the circuit board to check that all components are assembled correctly.
(4) AXI: AXI belongs to the scope of non-contact non-destructive testing and has the ability to see through heavy metals such as lead-tin alloys AXI can identify solder joints with a pitch of 0.2MM. Now AXI has gradually entered the commercial category.
