文档介绍：Control your processwith WW/sq/milmeasurementsIncorporating the importantWW/square/mil (25ìm) measurementtool is important for the followingreasons:?Film thickness optimization and control?Cure optimization and control?Ink quality verification?Reduced scrap costs?/square/milclarifies film thickness, resistance, adhesion, cohesion, and cure is straightforward: Your resulting ?/square/mil value should closely matchthe Acheson certified value for that batch of ink. This will require an optimum inkdeposit, optimum cure rate, and consistent ink ease of measurement, incorporate a resistance test stripe into your artwork havinga length to width ratio over 50:1, or 50 squares. You can also measure the circuitry if astraight measurable stripe is method: length (l) of the stripe, and divide by width (w) to calculate number the resistance reading (in ohms) across the stripe by the number of will give an approximation of ohms per . Multiply ohms per square by coating thickness (t) to convert to ohms per square at 1mil (25 ìm dry film thickness), . ?/square/mil (25 ìm).CircuitMaterialsExample: from end to end = 60 mmWidth of trace = mm60 mm ÷ = 100 reading from end to end = ? ?÷ 100 squares = ?/ film thickness = mi
