Decoding the Designation: "7628"
The term "7628 E Glass Electronic Fiberglass Fabric" refers to one of the most common and important workhorse materials in the printed circuit board (PCB) industry.
Here is a detailed breakdown of its specifications, properties, and applications.
Decoding the Designation: "7628"
"7628": This is a style number, an industry-standard code that defines the specific construction of the woven fabric.
It specifies the yarn type (e.g., filament count and twist), the thread count (ends per inch in warp and weft), and the resulting thickness and weight.
A style 7628 fabric is characterized by its heavy weight and thick build.
"E Glass": Denotes the glass composition. "E" stands for Electrical, meaning it is made from the standard alumino-borosilicate glass formulation optimized for excellent electrical insulation.
"Electronic Fiberglass Fabric": Confirms its primary application is for the electronics industry, specifically as a reinforcement for PCBs.
Key Properties and Specifications
A typical 7628 E-glass fabric has the following characteristics:
Areal Weight: Approximately 200 - 210 grams per square meter (g/m²). This makes it one of the heaviest standard fabrics.
Thickness: Approximately 0.185 - 0.200 mm (or 7.3 - 7.9 mils).
Weave Style: A plain weave, which provides good stability and low yarn slippage.
Thread Count: Typically around 17x12 (17 warp yarns and 12 weft yarns per inch).
Key Properties:
High Mechanical Strength: Its thick, heavy construction provides exceptional rigidity and dimensional stability to the final PCB laminate.
Good Electrical Insulation: Inherits the excellent dielectric properties of E-glass.
Controlled Dielectric Constant (Dk): While not a "low-loss" material like 2116 or 3814+, its electrical properties are stable and predictable for many applications.
Thermal & Chemical Resistance: Withstands PCB manufacturing processes like soldering and exposure to chemicals.
