Mipikisano dera matabwa pakati TG150 8 zigawo

Tiyeni tidziwitse zina za pcb mkuwa makulidwe.

Mkuwa zojambulazo monga pcb conductive thupi, mosavuta adhesion kwa kutchinjiriza wosanjikiza, dzimbiri mawonekedwe dera chitsanzo.The makulidwe a zojambulazo mkuwa amasonyezedwa mu oz(oz), 1oz = 1.4mil, ndi makulidwe ambiri a zojambulazo mkuwa amasonyezedwa mu kulemera pa unit. dera ndi chilinganizo: 1oz=28.35g/FT2(FT2 ndi masikweya mapazi, 1 lalikulu phazi =0.09290304㎡).
Mayiko pcb mkuwa zojambulazo ambiri ntchito makulidwe: 17.5um, 35um, 50um, 70um.Nthawi zambiri, makasitomala sapanga mawu apadera popanga pcb.Makulidwe amkuwa a mbali imodzi ndi iwiri nthawi zambiri amakhala 35um, ndiye kuti, 1 amp mkuwa.Inde, ena mwa matabwa enieni adzagwiritsa ntchito 3OZ, 4OZ, 5OZ ... 8OZ, ndi zina zotero, malinga ndi zofunikira za mankhwala kuti asankhe makulidwe oyenera amkuwa.

Makulidwe ambiri amkuwa a bolodi limodzi ndi mbali ziwiri za PCB ndi pafupifupi 35um, ndipo makulidwe ena amkuwa ndi 50um ndi 70um.Kukhuthala kwa mkuwa kwa mbale ya multilayer nthawi zambiri kumakhala 35um, ndipo makulidwe amkati amkuwa ndi 17.5um.Ntchito Pcb bolodi mkuwa makulidwe makamaka zimadalira ntchito PCB ndi voteji chizindikiro, kukula panopa, 70% ya bolodi dera amagwiritsa 3535um mkuwa zojambulazo makulidwe.Zachidziwikire, chifukwa chapano ndi bolodi lalikulu kwambiri, makulidwe amkuwa adzagwiritsidwanso ntchito 70um, 105um, 140um (ochepa kwambiri)
Pcb bolodi ntchito ndi osiyana, ntchito makulidwe mkuwa ndi osiyana.Monga ogula wamba ndi zinthu zoyankhulirana, gwiritsani ntchito 0.5oz, 1oz, 2oz;Ambiri amakono, monga mankhwala voteji, bolodi magetsi ndi zinthu zina, zambiri ntchito 3oz kapena pamwamba ndi wandiweyani mkuwa mankhwala.

Ndondomeko ya lamination ya matabwa a dera nthawi zambiri imakhala motere:

1. Kukonzekera: Konzani makina opangira laminating ndi zipangizo zofunikira (kuphatikizapo matabwa ozungulira ndi zojambula zamkuwa kuti zikhale laminated, mbale zosindikizira, etc.).

2. Kuyeretsa: Kuyeretsa ndi kuchotseratu oxidize pamwamba pa bolodi la dera ndi zojambulazo zamkuwa kuti zikanikizidwe kuti zitsimikizire kuti ntchito yabwino ya soldering ndi kugwirizana.

3. Lamination: Laminate zojambulazo zamkuwa ndi bolodi loyang'anira dera malinga ndi zofunikira, kawirikawiri wosanjikiza umodzi wa bolodi wozungulira ndi wosanjikiza umodzi wa zojambulazo zamkuwa zimayikidwa mosinthana, ndipo potsirizira pake gulu la dera lamagulu ambiri limapezeka.

4. Kuyika ndi kukanikiza: ikani bolodi la dera lopangidwa ndi laminated pamakina osindikizira, ndikusindikiza bolodi yozungulira yamagulu ambiri poyika mbale yosindikizira.

5. Njira yopondereza: Pansi pa nthawi yokonzedweratu ndi kukakamizidwa, bolodi la dera ndi zojambulazo zamkuwa zimapanikizidwa pamodzi ndi makina osindikizira kuti agwirizane mwamphamvu.

6. Chithandizo choziziritsa: Ikani bolodi lopanikizidwa pagawo lozizirira kuti lizizizira, kuti lifike kutentha kokhazikika komanso kupanikizika.

7.Subsequent processing: Onjezani zotetezera pamwamba pa bolodi la dera, pangani ndondomeko yotsatira monga kubowola, kuyika pini, ndi zina zotero, kuti mutsirize ntchito yonse yopangira gulu la dera.
