Kufunika kwa okhwima kusintha kwa PCB cannot be underestimated in PCB manufacturing. Chifukwa chimodzi ndichomwe zimapangitsa kuti miniaturization ichitike. Kuphatikiza apo, kufunikira kwa ma PCBS okhwima kukukulira chifukwa cha kusinthasintha komanso magwiridwe antchito a msonkhano wa 3D. Komabe, si onse opanga ma PCB omwe amatha kuthana ndi zovuta kupanga ndi okhwima njira zopangira PCB. Makina osindikizira osinthika pang’ono amapangidwa ndi njira yomwe imachepetsa makulidwe a bolodi yolimba mpaka 0.25mm +/- 0.05mm. Izi, zimathandizanso kuti board azigwiritsidwa ntchito pazinthu zomwe zimafuna kupindika komiti ndikuyika mkati mwa nyumbayo. The plate can be used for one-time bending installation and multi-bending installation.

Nayi chidule cha zina mwazomwe zimapangitsa kuti zikhale zapadera:

FR4 theka – kusintha kwa PCB

L Chofunika kwambiri chomwe chimagwira ntchito bwino ndikuti chimasinthasintha ndipo chimatha kusintha malo omwe alipo.

L Kusinthasintha kwake kumakulitsidwa ndikuti kusinthasintha kwake sikulepheretsa kufalikira kwa ma siginolo.

L Ndiopepuka.

Mwambiri, ma PCBS osasinthasintha amadziwikanso ndi mtengo wawo wabwino chifukwa njira zawo zopangira ndizogwirizana ndi kuthekera komwe kulipo kale.

L Amasunga nthawi yopanga komanso nthawi yamisonkhano.

L Ndi njira zodalirika kwambiri, makamaka chifukwa amapewa mavuto ambiri, kuphatikiza zingwe ndi kuwotcherera.

Njira zopangira PCB

The main manufacturing process of FR4 semi-flexible printed circuit board is as follows:

Njirayi imafotokoza izi:

L Zofunika kudula

L Kujambula kwamafilimu owuma

L Yoyendera makina oyendera

L Browning

L laminated

L Kuunika kwa X-ray

L kuboola

L kusanja kwamagetsi

L Graph kutembenuka

L etching

L Screen yosindikiza

L Kuwonetsa komanso chitukuko

L zinthu mopupuluma kumaliza

L Kuzama kwa mphero

L Mayeso amagetsi

L Kulamulira kwabwino

L phukusi

Kodi mavuto ndi njira zotheka kupanga PCB?

Vuto lalikulu pakupanga ndikutsimikizira kulondola ndi kuzama kwa kulolerana kwa mphero. Ndikofunikanso kuwonetsetsa kuti palibe ming’alu ya utomoni kapena mafuta omwe angayambitse zovuta zilizonse. Izi zimaphatikizapo kuwunika zotsatirazi mukamayendetsa kaye mozama:

L makulidwe

L utomoni wokhutira

L Mphero kulolerana

Kuzama kulamulira mphero mayeso A

Mphero yolimba idachitidwa mwa kupanga mapu kuti agwirizane ndi makulidwe a 0.25 mm, 0.275 mm ndi 0.3 mm. Bungweli litatulutsidwa, liyesedwa kuti liwone ngati lingapirire 90 degree bending. Nthawi zambiri, ngati makulidwe otsalawo ndi 0.283mm, fiber yamagalasi imawonedwa kuti yawonongeka. Therefore, the thickness of the plate, the thickness of the glass fiber and the dielectric condition must be taken into account when conducting deep milling.

Kuzama kulamulira mphero mayeso B

Kutengera pamwambapa, ndikofunikira kuonetsetsa kuti makulidwe amkuwa a 0.188mm mpaka 0.213mm pakati pazotchinga zotchinga ndi L2. Chisamaliro choyenera chimafunikiranso kutengedwa kuti kumenyedwe kulikonse komwe kungachitike, komwe kumakhudza kufanana kwake konse.

Kuzama kulamulira mphero mayeso C

Mphero yoyendetsera kuzama inali yofunikira kuwonetsetsa kuti miyesoyo yakhazikitsidwa ku 6.3 “x10.5” pambuyo poti gulu lazithunzilo latulutsidwa. After this, survey point measurements are taken to ensure that 20 mm vertical and horizontal intervals are maintained.

Special fabrication methods ensure that the depth control thickness tolerance is within ±20μm.
