Connector Configuration Fundamentals: What Each Attribute Means

Before diving into specific configurations, let's establish foundational knowledge about board to board connector attributes. Understanding these fundamentals helps you communicate effectively with buyers and configure products that match market expectations.

Pitch Size refers to the distance between adjacent connector pins, measured in millimeters. This is perhaps the most critical specification. Common pitch sizes include:

Pitch Size Categories and Applications

Pitch Category	Typical Range	Common Applications	Manufacturing Considerations
Fine Pitch	0.4mm - 1.0mm	Smartphones, wearables, high-density PCBs	Requires precision manufacturing, higher cost, automated assembly
Standard Pitch	1.27mm - 2.54mm	Industrial equipment, consumer electronics, prototyping	Widely available, cost-effective, manual assembly possible
Heavy Pitch	3.5mm - 5.08mm+	Power applications, high-current systems	Lower density, higher current capacity, robust mechanical design

Pitch selection directly impacts PCB layout density, assembly method, and cost structure. Fine pitch connectors command premium pricing but require advanced manufacturing capabilities.

Mounting Type determines how the connector attaches to the PCB. The two primary options are:

Surface Mount Technology (SMT) dominates modern electronics manufacturing. SMT connectors sit on the PCB surface and are soldered using reflow processes. They enable automated assembly, support high-density layouts, and are compatible with pick-and-place machines. According to MarketsandMarkets, SMT represents the largest mounting type segment in the board to board connector market ^[1].

Through-Hole Technology (THT) connectors have pins that pass through PCB holes and are soldered on the opposite side. While less common in high-volume consumer electronics, THT remains preferred for applications requiring superior mechanical strength, such as industrial equipment subject to vibration or thermal cycling.

Connector Orientation defines the spatial relationship between mated boards:

Parallel (Stacking/Mezzanine): Boards stack face-to-face, minimizing overall height. Mezzanine connectors dominated the market in 2024 ^[1]. Ideal for space-constrained designs like mobile devices.
Perpendicular (Right Angle): Boards connect at 90 degrees. Common in applications where board stacking isn't feasible.
Coplanar: Boards connect edge-to-edge in the same plane. Used for board expansion or modular designs.
