Q1: What is the minimum thickness of the alumina substrates?
Our standard thickness: 0.25mm, 0.30mm, 0.38mm, 0.50mm, 0.635mm, 0.76mm, 0.80mm, 0.89mm, 1.0mm, 1.5mm and 2.0mm. Minimum thickness to be 0.1mm. Welcome to inquire about customized services.
Q2: Do you provide free samples?
Samples of standard sizes are free, and we only charge for shipping. If customization is required, we only collect sample fee for MOQ.
Q3: How long is your delivery time?
If it is one of our standard sizes and we have it in stock, we will ship it within 2 days. In other cases, the standard delivery time is generally 4-6 weeks.
Q4: How are ceramic substrates packaged to avoid breakage?
Because ceramics are hard and brittle materials, each of our products will be packed in a safe and reliable way to avoid damage during transportation.
Q5: Can alumina substrates be polished?
Yes, lapping and polishing will provide the desired flatness and thickness tolerance, with a surface roughness generally below Ra0.05.
Q6: What is the camber of your alumina substrates?
Our alumina substrates are 100% inspected for camber. The camber is less than 5‰ for 96% alumina with a thickness below 0.3mm. For 96% alumina with other thicknesses and for other purities, the camber is less than 3‰.
