In small batch PCB assembly, cost control is a crucial link. The following are some effective strategies for cost control of small-batch PCB assembly:
First, cost control in the design phase
Component selection
Cost-effective consideration: under the premise of meeting the functional requirements of the product, choose cost-effective components. Avoid excessive pursuit of high performance indicators and use of expensive components. For example, for microcontrollers in ordinary consumer electronics products, if the product function does not require extreme computing speed and processing power, choose a low-end and mature and stable model.
Strong versatility: give priority to components with strong versatility and sufficient market supply to reduce procurement costs, facilitate later maintenance and replacement, and reduce production delay costs caused by shortages of components.
PCB design optimization
Minimize the size and number of layers: accurately plan the shape and size of the PCB to avoid material waste caused by excessive design. At the same time, under the premise of ensuring electrical performance, the number of PCB layers is minimized to reduce manufacturing costs.
Layout and routing optimization: Reasonable layout and routing can both improve the performance of the PCB and reduce the cost. For example, the closely related components are placed together to shorten the length of the connection line and reduce wire consumables; Simple and direct wiring method is adopted to avoid twists and turns and reduce line length.
Integrate DFM concept: Integrate the design for manufacturability (DFM) concept in the design process to ensure that component spacing, test point Settings, etc. meet the requirements of automated patch and plug-in production, and avoid problems such as low production efficiency and defective rate caused by design errors.
Second, the cost control of raw material procurement
Centralized purchasing
Through centralized procurement, increase the purchase volume to obtain price concessions from suppliers. At the same time, establish long-term cooperative relations with suppliers with good reputation and stable quality to reduce procurement costs, reduce the rate of defective products, and reduce quality control costs.
Alternative material
Under the premise of meeting the performance requirements, find alternative materials with higher cost performance. For example, the use of domestic components instead of imported components to reduce procurement costs.
Third, cost control in the production process
Improve production efficiency
Automated production: The introduction of automated production equipment, such as automatic placement machines, automatic reflow furnaces, etc., can greatly improve production efficiency and reduce labor costs.
Optimize the production process: Through lean production, Six Sigma and other management methods, optimize the production process to reduce waste and waiting time in the production process.
Staff training: Regularly conduct skills training for employees to improve their operational proficiency and production efficiency.
Rational use of outsourcing services
For small scale or do not have a complete production capacity of electronic equipment manufacturers, the rational use of outsourcing services is also an effective way to save PCBA manufacturing costs. Clarify the rights and obligations of both parties in the outsourcing contract, including key terms such as price, quality and delivery time, so as to avoid disputes in the later stage. Establish long-term cooperation with outsourcing service providers, you can get more favorable prices and better service.
Intelligent Mosaic technology
For small batch PCB assembly, intelligent Mosaic technology can significantly improve board utilization. Through the intelligent assembly system, the irregular shape of the circuit board is optimized and combined, and the utilization rate of the board is greatly improved. At the same time, the unified specification of the assembly scheme can also shorten the production line change time, reduce the cost of manual debugging.
Fourth, quality control and cost management
Strict quality inspection
In the raw material storage, production process and product delivery and other links, carry out strict quality testing to ensure product quality. Through the establishment of a perfect quality traceability system, the quality problems in the production process are tracked and analyzed in order to improve in time and avoid the cost increase caused by quality problems.
Implement cost control and audit
Establish a sound cost control system to monitor and record all costs in the production process in real time. Audit PCBA manufacturing cost regularly, analyze cost composition and change trend, in order to adjust cost control strategy in time. Incorporate cost control into employees' performance appraisal system and motivate employees to actively participate in cost control activities.
Fifth, other cost control measures
Cross-departmental collaboration
Set up a special team to ensure the smooth progress of cost control strategy. Through cross-department collaboration, information sharing and resource integration are realized to improve cost control effect.
Continuous improvement
Establish a feedback mechanism to continuously optimize production processes and management methods. Pay attention to the industry dynamics and new technology development, and actively explore new methods and new processes to reduce costs.
