Understanding the Dynamics of PCB Board Pricing
- Material Selection:
- Different materials, such as FR-4 and CEM-3, impact prices.
- Varied sheet thickness (0.6mm to 3.0mm) and copper thickness (½Oz to 3 Oz) contribute to cost differences.
- Diverse solder mask inks, from thermosetting to photosensitive green oil, result in price variations.
- Production Process Variation:
- Different processes, like gold-plated vs. tin-sprayed boards, milling vs. punching boards, and silk-printed vs. dry film lines, lead to distinct costs.
- Complexity and Difficulty:
- The difficulty of PCBs, determined by factors like hole diameter, line width, and spacing, influences costs.
- Higher complexity and difficulty lead to increased scrap rates and production costs.
- Customer Requirements:
- Varied customer demands, such as IPC-A-600E class requirements, impact production rates and costs.
- Stringent requirements may increase costs, affecting final product prices.
- Manufacturer Differences:
- Different PCB manufacturers with varying equipment and technical levels result in different costs.
- Process preferences, like gold-plated vs. tin-sprayed panels, contribute to price disparities.
- Payment Method Impact:
- PCB prices are adjusted based on payment methods, causing variations of 5% to 10%.
- Regional Price Differences:
- Geographical location influences prices, with variations from south to north.
- Regional differences contribute to the overall diversity in PCB prices.
Basic Components of PCB Board Pricing:
- Plate cost (varying with different plate types)
- Drilling costs (affected by hole number and aperture size)
- Process cost (linked to the difficulty of different processes)
- Labor, water, and electricity, plus management costs (factory-specific cost control factors)
In conclusion, understanding these factors provides insights into the multifaceted nature of PCB board pricing. Raw material prices have stabilized, minimizing the likelihood of increases.
