Construction & Spécifications de matériau
Layer Stack-Up:
Ce 2 layer rigid PCB structure is as follows (top to bottom):
-
Top Solder Mask (Blanc): Insulating layer to prevent solder bridges.
-
Top Copper Layer (1 once, ~35µm): Etched to form conductive traces and pads.
-
Insulating Core Substrate (FR-4, Tg150): Provides mechanical support and electrical insulation.
-
Bottom Copper Layer (1 once, ~35µm): Etched to form bottom-layer circuitry.
-
Bottom Solder Mask (Blanc): Insulating protective layer.
-
Silkscreen Legend (Noir): Component designators, logos, and markings.
Key Materials:
-
Base Laminate: FR-4TG150. This denotes a flame-retardant glass-reinforced epoxy laminate with a Glass Transition Temperature (Tg) of 150°C. It offers superior mechanical strength, isolation électrique, and thermal reliability for a rigid printed circuit board, making it the industry’s most cost-effective choice.
-
Feuille de cuivre: Standard 1-ounce (once) Electro-Deposited copper for optimal conductivity and current carrying capacity.
-
Finition de surface: Lead-Free Hot Air Solder Leveling (HASL). 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.

Directives de conception & Operational Principle
Critical Design Considerations:
-
Via la conception: Maximize the routing space of your double sided Conception de circuits imprimés by strategically placing Plated Through-Holes (PTHs) for inter-layer connections.
-
Largeur de trace / espacement: For 1oz copper, a standard minimum trace/space is 6mil/6mil (~0.15mm) to ensure reliable manufacturability and current capacity.
-
Tampon & Hole Annular Ring: Ensure adequate pad size relative to the drill hole to guarantee a strong connection for Assemblage de circuits imprimés et fiabilité.
-
Masque de soudure & Écran à soigneux: White solder mask aids visual inspection during Assemblage SMT, while clear black silkscreen is crucial for Prototypage PCB 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. Plaqué à travers les trous (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.
Caractéristiques de performance & Avantages
-
Haute fiabilité: Le FR-4 TG150 substrate ensures stable performance in environments below its Tg, offering excellent thermal and mechanical stability for a rigid circuit board.
