This product is a double sided circuit board constructed with copper clad laminate on both sides of an insulating FR-4 core. Electrical connection between layers is achieved via plated through-holes (PTH). ال 1.60مم (approximately 1/16 inch) board thickness is an industry-standard, offering excellent mechanical stability.

بناء & مواصفات المواد

Layer Stack-Up:

هذا 2 layer rigid PCB structure is as follows (top to bottom):

1. Top Solder Mask (أبيض): Insulating layer to prevent solder bridges.

2. Top Copper Layer (1 أوقية, ~35µm): Etched to form conductive traces and pads.

3. Insulating Core Substrate (فر-4, Tg150): Provides mechanical support and electrical insulation.

4. Bottom Copper Layer (1 أوقية, ~35µm): Etched to form bottom-layer circuitry.

5. Bottom Solder Mask (أبيض): Insulating protective layer.

6. Silkscreen Legend (أسود): Component designators, logos, and markings.

Key Materials:

• Base Laminate: FR-4 TG150. This denotes a flame-retardant glass-reinforced epoxy laminate with a Glass Transition Temperature (تيراغرام) of 150°C. It offers superior mechanical strength, العزل الكهربائي, and thermal reliability for a rigid printed circuit board, making it the industry’s most cost-effective choice.

• احباط النحاس: Standard 1-ounce (أوقية) Electro-Deposited copper for optimal conductivity and current carrying capacity.

• الانتهاء من السطح: Lead-Free Hot Air Solder Leveling (ينزف). A cost-effective and reliable PCB surface finish that provides excellent solderability, good shelf life, and robust protection against oxidation.

• Inks: High-quality photo-imageable white solder mask ink and durable black epoxy silkscreen ink.

إرشادات التصميم & Operational Principle

اعتبارات التصميم الحرجة:

1. Via Design: Maximize the routing space of your double sided تصميم ثنائي الفينيل متعدد الكلور by strategically placing Plated Through-Holes (PTHs) for inter-layer connections.

2. تتبع العرض/التباعد: For 1oz copper, a standard minimum trace/space is 6mil/6mil (~0.15mm) to ensure reliable manufacturability and current capacity.

3. Pad & Hole Annular Ring: Ensure adequate pad size relative to the drill hole to guarantee a strong connection for تجميع ثنائي الفينيل متعدد الكلور والموثوقية.

4. قناع اللحام & Silkscreen: White solder mask aids visual inspection during SMT assembly, while clear black silkscreen is crucial for PCB prototyping and repair.

Operational Principle:

A PCB does not generate function but enables it through its predefined conductive pathways. The etched copper traces replace discrete wiring, providing electrical connections between components. The insulating FR-4 substrate prevents short circuits. Plated through-holes (PTHs) serve as vertical conduits, connecting the top and bottom PCB copper layers, thereby doubling the available routing area compared to a single-sided board and increasing design flexibility.

خصائص الأداء & Advantages

• High Reliability: ال FR-4 TG150 substrate ensures stable performance in environments below its Tg, offering excellent thermal and mechanical stability for a rigid circuit board.

• Excellent Electrical Properties: Low dielectric constant and dissipation factor support the signal integrity requirements of most digital and analog circuits.
