Product Definition & Clasificare

Technical Classification:

• By Layer Count: Double-Sided PCB / Two Layer PCB

• By Substrate Rigidity: Rigid PCB

• By Base Material: Glass Epoxy (FR-4) PCB

• By Flammability Rating: UL94 V-0 (inherent to FR-4)

• By Assembly Compatibility: Tehnologie prin gaură (THT) and Surface-Mount Technology (Smt) capable PCB.

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). The 1.60mm (approximately 1/16 inch) board thickness is an industry-standard, offering excellent mechanical stability.

Construction & Specificații materiale

Layer Stack-Up:

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

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

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

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

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

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

6. Silkscreen Legend (Negru): 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 (TG) of 150°C. It offers superior mechanical strength, electrical insulation, and thermal reliability for a rigid printed circuit board, making it the industry’s most cost-effective choice.

• Folie de cupru: Standard 1-ounce (Oz) Electro-Deposited copper for optimal conductivity and current carrying capacity.

• Surface Finish: Lead-Free Hot Air Solder Leveling (Sângera). 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.

Ghid de proiectare & Operational Principle

Critical Design Considerations:

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

2. Lățimea/Spațierea traseului: 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 Ansamblu PCB and reliability.

4. Masca de lipit & Mătase: White solder mask aids visual inspection during ansamblu SMT, 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.

Caracteristici de performanță & Advantages

• Fiabilitate ridicată: The 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.

• High Manufacturability: The 1.6mm standard PCB thickness şi Lead-Free HASL process are mature, ensuring high yield, cost control, and fast lead times.

• Superior Solderability: The HASL finish offers a flat, wettable surface ideal for both through-hole soldering şi SMT soldering processes.

• Clear Identification: High-contrast white solder mask with black legend facilitates efficient PCB inspecţie, testarea, and rework.

• Environmental Compliance: Lead-Free HASL finish complies with RoHS and other environmental directives.
