Embodiment 1
[0045] A method for manufacturing a ceramic-based interconnected flexible circuit board of the present invention comprises the following steps:
[0046] A. Making aluminum nitride ceramic circuit boards
[0047] a1. Make the inner layer graphics on the pretreated aluminum nitride ceramic copper clad laminate;
[0048] It mainly includes: incoming material inspection → degreasing → pickling → drying → film pressing → exposure → development → etching → film removal → drying and other processes;
[0049] The specific method is: clean the surface of the aluminum nitride ceramic copper clad substrate that has passed the inspection, use sodium persulfate to micro-etch the copper clad layer of the aluminum nitride ceramic copper clad substrate, and remove the oil and surface on the copper clad layer. Compared with cleaning the circuit board substrate by physical methods, it is more effective in preventing damage to the aluminum nitride ceramic copper-clad substrate. The micro-etched...

[0097] A method for manufacturing a ceramic-based interconnected flexible circuit board of the present invention comprises the following steps:
[0098] A. Making aluminum nitride ceramic circuit boards
[0099] a1. Make the inner layer graphics on the pretreated aluminum nitride ceramic copper clad laminate;
[0100] It mainly includes: incoming material inspection → degreasing → pickling → drying → film pressing → exposure → development → etching → film removal → drying and other processes;
[0101] The specific method is: clean the surface of the aluminum nitride ceramic copper clad substrate that has passed the inspection, use ammonium persulfate to micro-etch the copper clad layer of the aluminum nitride ceramic copper clad substrate, and remove the oil and surface on the copper clad layer. Compared with cleaning the circuit board substrate by physical methods, it is more effective in preventing damage to the aluminum nitride ceramic copper-clad substrate. The micro-etch...
