FAQ
| Q: What is your delivery date? CESGATE: The general sample delivery time is 6 working days for single and double-sided boards, 7 working days for 4-layer boards, and an additional working day for every 2 layers. However, if there are special processes, additional working days will be added according to the situation. Generally, the delivery time for mass production is 10 working days for single and double-sided panels, and 15 working days for multi-layer panels. However, if there is a special process or more than a certain number of working days, the working days will be additionally increased according to the situation; you can also pay the urgent fee to shorten the number of days, please contact Contact the business specially proposed, depending on the individual situation to provide expedited days. |
| Q: What is the difference between the HDI board and the general
circuit board? CESGATE: Most of HDI use laser to form holes, while general circuit boards only use mechanical drilling, and HDI boards are manufactured by the build-up method (Build Up), so more layers will be added, while general circuit boards are only added once. |
| Q: What are the types of solder mask? CESGATE: There are traditional epoxy resin IR baking type, UV curing type, Liquid Photo Imageable Solder Mask and Dry film solder mask. Currently, the liquid solder mask is the main type. |
| Q: What are the common substrates of CESGATE? A:Tg-140: ISOLA FR402 / NAN-YA NP-140 Tg-150: ISOLA IS400 / NAN-YA NP-155 Tg-170~180: ISOLA 370HR / NPN-YA / NAN-YA NP-175F |
