1. Q: What is a red oil hard board PCB?
A: Red oil hard board PCB refers to a rigid printed circuit board that uses red solder mask oil (commonly known as "red oil") as the surface solder mask layer.
2. Q: What are the main application fields of red oil hard board PCBs?
A: It is mainly used in consumer electronics (such as power supplies, audio equipment), industrial control equipment, automotive electronics (non-high-temperature core components), medical devices (external auxiliary equipment), and household appliances. It is especially suitable for products that require obvious board surface color distinction or brand-specific color positioning.
3. Q: What is the minimum order quantity (MOQ) for red oil hard board PCBs?
A: The minimum order quantity is 1 piece (with a maximum single-piece area of 5 square meters).The larger the order quantity or total area, the more favorable the unit price.
4. Q: Do your red oil hard board PCBs have relevant quality certifications? How to ensure the quality of the red oil layer?
A: We hold authoritative certifications such as ISO 9001, UL, CE, and RoHS. For the red oil layer, we have special quality control processes: strictly select high-quality red solder mask oil, adopt automatic screen printing technology, and conduct 100% inspections on the red oil layer (including adhesion, thickness uniformity, and scratch resistance) before delivery to ensure no peeling, blistering, or color fading.
5. Q: What files do I need to provide for customizing red oil hard board PCBs?
A: You need to provide complete Gerber files (including circuit layer, solder mask layer, silk screen layer, drilling layer, etc.) and BOM list. If SMT processing is required, you also need to provide component placement drawings and component specifications.
6. Q: What payment methods are available for red oil hard board PCB orders?
A: For small orders, samples, or urgent payments, Western Union or PayPal is acceptable; for large orders, we recommend T/T (telegraphic transfer) to ensure the fund safety of both parties.
