Frequently Asked Questions
Q1
What do the dimensional tolerances mean in this specification table?
Dimensional tolerances indicate the allowable deviation from the specified length and width measurements. For example, a tolerance of ±0.1 mm means the actual dimension can be 0.1 mm larger or smaller than the stated size, ensuring consistent fit and performance in precision applications.
Q2
Why do larger sizes have wider dimensional tolerances?
As the piece size increases, maintaining the same tight tolerance becomes more technically challenging during manufacturing. Larger substrates are more susceptible to thermal expansion, cutting variation, and material stress, which is why tolerances naturally widen from ±0.1 mm for small pieces to ±0.5 mm for larger 200×200 mm pieces.
Q3
What is the thinnest available standard thickness, and which sizes support it?
The thinnest standard thickness available is 0.5 mm, which is supported by the 10×10 mm and 20×20 mm sizes. Smaller dimensions are better suited for ultra-thin applications due to structural stability considerations at such minimal thickness levels.
Q4
Can I order a custom size or thickness not listed in the table?
Yes, custom sizes and thicknesses beyond the standard specifications listed in the table are available upon request. Please reach out to our technical team with your exact requirements, and we will assess feasibility, applicable tolerances, and lead times for your custom order.
Q5
What does a thickness tolerance range like ±0.05～±0.1 mm indicate?
A thickness tolerance range such as ±0.05～±0.1 mm means the achievable tolerance depends on the specific thickness selected within that size. Thinner pieces (e.g., 0.5 mm) typically achieve tighter tolerances like ±0.05 mm, while slightly thicker pieces may fall within the ±0.1 mm range, reflecting process capability at different thickness levels.
Q6
Are these specifications suitable for high-precision industrial or electronic applications?
Yes. The tight dimensional and thickness tolerances listed — particularly for smaller sizes such as 10×10 to 50×50 mm with tolerances as precise as ±0.05 mm — make these specifications well-suited for high-precision industries including electronics, semiconductors, optics, and advanced manufacturing where exact dimensions are critical.
