Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 storey density multilayer professional supplier, to provide customers with high-precision high quality Shenzhen board, quality assurance, reasonable prices. Hard board should have a certain thickness, since the flexible portion is thin and no glass cloth, after the affected environment and thermal shock, it changes with the rigid portion is a difference, combined with the advantages of soft and hard board, if there is no rigid part a certain thickness or hardness, the difference will show very clearly, using the process will produce more serious warpage, weld and the use of influence, if the rigid portion has a certain thickness or hardness, the difference may be appears to be negligible, the overall flatness does not change with the flexible part of those changes, can ensure the welding and the use of, Guangdong Flex PCB, if it appears too thick thick rigid portion uneconomical, proved 0.8 ~ 1.0mm The thickness is more appropriate.

Even after using the positioning holes punched OPE monolithic lamination interlayer before the treatment also has a great influence on the position. First, since the polyimide material resistant to alkali, produce swelling in alkaline solution. Therefore, when a black, brown treatment process, the Shenzhen rigid-flex circuit board, in a strongly basic procedures such as degreasing, soft Hard PCB company, black, brown and so appropriate to reduce the temperature, decrease the time. As a result of non-adhesive layer on the substrate, without regard to changes in the adhesive layer in lye, this method is feasible. Secondly, single post-oxidation treatment should be avoided vertically baking, baking mode level should be taken, can reduce bending, try to remain flat. As much as possible to shorten the baking time loading mode to prevent moisture absorption monolithic again. Ring width requirements to ensure the accuracy of the outer layer of pattern transfer.
