1. Description of customization requirements: Customers need to provide specific details of the circuit board application, including but not limited to usage environment, temperature requirements, bending times, impedance control, etc., to ensure that the customized four-layer soft-hard board can meet specific working conditions. and performance indicators. 2. Technical requirements: Submit clear circuit diagrams, dimensional specifications and performance requirements, including detailed descriptions of line width/line spacing, aperture size, board material, surface treatment specifications, copper thickness and other parameters, as well as the required international certification standards. . 3. Quantity requirements and delivery deadline: Clearly indicate the minimum order quantity and batch requirements for customized products, and stipulate the delivery deadline. For sample verification before mass production, a time frame needs to be established to coordinate the sample production and testing cycles. 4. Customized samples and customized prices: State the cost of sample production and the estimated price for bulk orders. Pricing plans should take into account factors such as materials, process complexity, and order size. The specific cost of the sample will be given after confirming the customization requirement, and it will be clear whether the sample cost will be deducted from the final large order. 5. Payment method and customization agreement: Determine a clear payment process, including advance payment ratio, payment nodes, and conditions for product ownership transfer after full payment. At the same time, a customized agreement needs to be signed to ensure that the rights and obligations of both parties are clear, as well as relevant agreements on confidentiality and intellectual property rights. Supplementary instructions: Ensure the accuracy and authenticity of all customized information, technical parameters and commercial terms, and avoid any exaggeration or misleading information for the purpose of establishing long-term, mutually beneficial business cooperation.
