Product Definition & 分類

技術分類:

• レイヤーカウントごとに: 両面PCB / Two Layer PCB

• By Substrate Rigidity: リジッドPCB

• ベース素材によって: Glass Epoxy (FR-4) プリント基板

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

• By Assembly Compatibility: スルーホールテクノロジー (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 (約 1/16 インチ) ボードの厚さ is an industry-standard, offering excellent mechanical stability.

工事 & 材料仕様

レイヤースタックアップ:

これ 2 層リジッドPCB structure is as follows (top to bottom):

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

2. Top Copper Layer (1 オンス, ~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 オンス, ~35µm): Etched to form bottom-layer circuitry.

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

6. Silkscreen Legend (黒): 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, 電気断熱, and thermal reliability for a rigid printed circuit board, making it the industry’s most cost-effective choice.

• 銅箔: Standard 1-ounce (オンス) Electro-Deposited copper for optimal conductivity and current carrying capacity.

• 表面仕上げ: Lead-Free Hot Air Solder Leveling (出血). 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.

設計ガイドライン & 動作原理

設計上の重要な考慮事項:

1. Via Design: Maximize the routing space of your double sided プリント基板設計 by strategically placing Plated Through-Holes (pths) for inter-layer connections.

2. トレース幅/間隔: For 1oz copper, a standard minimum trace/space is 6mil/6mil (~0.15mm) to ensure reliable manufacturability and current capacity.

3. パッド & Hole Annular Ring: Ensure adequate pad size relative to the drill hole to guarantee a strong connection for PCBアセンブリ と信頼性.

4. はんだマスク & シルクスクリーン: White solder mask aids visual inspection during SMTアセンブリ, while clear black silkscreen is crucial for PCBプロトタイピング and repair.

動作原理:

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. メッキスルーホール (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.

性能特性 & 利点

• 高い信頼性: 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 厚さ そして 鉛フリー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 そして SMT soldering processes.

• Clear Identification: High-contrast white solder mask with black legend facilitates efficient プリント基板 検査, テスト, and rework.

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