MG Chemicals 503, Single Sided Copper Clad Boards , 1/16", 1 Oz Copper, 3"x5", Case of 5

MG Chemicals 503 is a single-sided copper-clad FR4 board for PCB prototyping and small production runs. Each nominal 3 × 5-inch blank combines a 1/16-inch glass-epoxy laminate with 1 oz copper cladding on one face. Its compact size provides engineers, electronics workshops, students and hobbyists with a starting surface for custom single-sided circuits. This listing supplies a case of five boards.

Best Uses / Applications

Single-sided PCB prototypes fitting a 3 × 5-inch starting blank.
Small production runs using an appropriate resist and copper-etching process.
Electronics education and hands-on circuit fabrication.
Compact custom layouts that do not require copper on both faces.

This is an unpatterned copper-clad laminate, not a finished circuit, pre-drilled perfboard or solderless breadboard. The manufacturer describes fabrication with an anti-etch PCB pen and copper etchant; select the complete fabrication process and handling controls appropriate to your design.

Key Features

Continuous woven glass cloth impregnated with epoxy resin.
FR4, described by the manufacturer as the flame-retardant version of G-10.
Single-sided 1 oz copper cladding, nominally 35 µm or 1.37 mil thick.
Less copper to remove than comparable 2 oz cladding, enabling quicker etching under comparable conditions.
DICY (dicyandiamide) cured system and UV-blocking construction.
Manufacturer describes easy cutting without specialized equipment; use a suitable method and follow the SDS.

Family specifications follow manufacturer documentation. Choose size, copper weight, laminate thickness and number of copper faces separately. For the same nominal 3 × 5-inch size with copper on both faces, compare 540. The family's thinner 1/2 oz copper (17 µm / 0.67 mil) and 1/32-inch laminate options do not describe 503.

Fabrication and Storage Guidance

Confirm layout dimensions, copper weight and layer requirements before fabrication. Apply a suitable etch resist, use a compatible copper etchant according to its instructions, and inspect the resulting circuit before assembly. Follow the board SDS and the instructions for each fabrication tool and chemical. Store unused boards in an airtight container at 18–27°C in a dry area away from sunlight and humidity.

Frequently Asked Questions

What size is MG Chemicals 503?

Each blank is nominally 3 × 5 inches, listed as 76 × 127 mm, with a 1/16-inch (1.6 mm) FR4 laminate.

Is copper present on both sides?

No. 503 has copper cladding on one face. The manufacturer's 540 is a double-sided option with the same nominal face dimensions.

What does 1 oz copper mean?

It is the copper cladding weight designation. The manufacturer gives a nominal thickness of 35 µm or 1.37 mil; it is not the total finished board weight.

How many boards are supplied?

This listing supplies a case of five 503 boards.

Is this ready for components?

It is an unpatterned blank rather than a finished circuit. Your design requires an appropriate fabrication process and any additional operations needed.

How does 503 differ from 506?

Both are single-sided 1 oz copper-clad FR4 with a listed 1/16-inch laminate. 503 is 3 × 5 inches; 506 is 4 × 6 inches.

Why choose 1 oz instead of 2 oz copper?

The manufacturer notes quicker etching because there is less copper to remove. Choose copper weight for the circuit's electrical and fabrication requirements, not etching speed alone.
