Muhiimadda PCB dabacsan oo adag lama dhayalsan karo wax soo saarka PCB. Mid ka mid ah sababaha ayaa ah isbeddelka xagga miniaturization. Intaa waxaa dheer, baahida loo qabo PCBS -da adag ayaa sii kordhaysa iyadoo ay ugu wacan tahay dabacsanaanta iyo shaqaynta kulanka 3D. Si kastaba ha noqotee, dhammaan soosaarayaasha PCB ma awoodaan inay la kulmaan habka wax -soo -saarka PCB ee dabacsan oo adag. Looxyada wareegga ee daabacan oo badhkood ah waxaa soo saaray hab hoos u dhiga dhumucda guddiga adag ilaa 0.25mm +/- 0.05mm. Tani, iyaduna, waxay u oggolaanaysaa guddiga in loo adeegsado codsiyada u baahan foorarsiga looxyada oo lagu dhejiyo gudaha guryaha. The plate can be used for one-time bending installation and multi-bending installation.

Halkan waxaa ah dulmar ku saabsan qaar ka mid ah astaamaha ka dhigaya mid gaar ah:

FR4 sifooyinka PCB ee badh -dabacsan

L Sifada ugu muhiimsan ee sida fiican ugu shaqaysa isticmaalkaaga ayaa ah inay tahay mid dabacsan oo la qabsan karta booska bannaan.

L Is -beddelkeeda waxaa kordhay xaqiiqda ah in dabacsanaanteedu aysan hor istaagin gudbinta signalkeeda.

L Sidoo kale waa khafiif.

Guud ahaan, PCBS-yada dabacsanaan leh ayaa sidoo kale lagu yaqaanaa qiimahooda ugu wanaagsan maxaa yeelay hab-dhismeedyadooda wax-soo-saarku waxay la jaan qaadayaan awooda wax-soo-saarka jira.

L Waxay badbaadiyaan wakhtiga naqshadeynta iyo waqtiga kulanka labadaba.

L Iyagu waa beddelaad aad loogu kalsoonaan karo, ugu yaraan maxaa yeelay waxay iska ilaaliyaan dhibaatooyin badan, oo ay ku jiraan murgacasho iyo alxanka.

Nidaamka samaynta PCB

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

Maxay yihiin dhibaatooyinka iyo xalalka suurtagalka ah ee wax soo saarka PCB?

Dhibaatada ugu weyn ee wax -soo -saarku waa in la hubiyo saxnaanta iyo xakamaynta dulqaadashada qoditaanka. Waxa kale oo muhiim ah in la hubiyo inaysan jirin dildilaaca xabagta ama saliidda oo sababi karta dhibaatooyin tayo leh. Tani waxay ku lug leedahay hubinta waxyaabaha soo socda inta lagu jiro xakamaynta qoto dheer:

L dhumucdiis

L Waxyaabaha ay ku jirto cusbi

L Dulqaadashada axdi qarameedka

Imtixaanka axdi qarameedka xakamaynta A

Dhumucda dhumucda waxaa lagu sameeyey habka khariidaynta si loo waafajiyo dhumucda 0.25 mm, 0.275 mm iyo 0.3 mm. Ka dib marka la sii daayo sabuuradda, waa la tijaabin doonaa si loo arko inay u adkaysan karto foorarsiga 90 darajo. Guud ahaan, haddii dhumucda soo hartay ay tahay 0.283mm, fiber galaaska waxaa loo tixgeliyaa inay waxyeello gaartay. 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.

Baadhitaanka xakamaynta qoto dheer B

Iyada oo ku saleysan kor ku xusan, waxaa lagama maarmaan ah in la hubiyo dhumucda naxaasta ah ee 0.188mm ilaa 0.213mm inta u dhaxaysa lakabka xayndaabka iibiya iyo L2. Daryeel habboon ayaa sidoo kale loo baahan yahay in la qaado si kasta oo warping ah oo dhici karta, taasoo saamaynaysa isku -ekaanta dhumucda guud.

Imtixaanka qoditaanka xakamaynta qoto dheer C

Qodista xakamaynta qotada ayaa muhiim u ahayd si loo hubiyo in cabbirrada loo dhigay 6.3 “x10.5” ka dib markii la sii daayay tusaalaha guddida. 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.
