Wopanga PCB Wopikisana

Kupanga matabwa PCB mkulu mlingo dera osati amafuna ndalama apamwamba luso ndi zipangizo, komanso kumafuna kudzikundikira zinachitikira amisiri ndi ogwira ntchito yopanga. Ndizovuta kwambiri kukonza kusiyana ndi matabwa amtundu wamitundu yambiri, ndipo zofunikira zake ndi zodalirika ndizokwera.

1. Kusankha zinthu

Ndi chitukuko cha zida zamagetsi zamagetsi zomwe zimagwira ntchito kwambiri komanso zimagwira ntchito zambiri, komanso kutumizira ma siginecha othamanga kwambiri komanso kuthamanga kwambiri, zida zamagetsi zamagetsi zimafunikira kuti pakhale kutayika kwa dielectric ndi dielectric, komanso CTE yotsika komanso kuyamwa kwamadzi otsika. . mlingo ndi bwino mkulu-ntchito CCL zipangizo kukwaniritsa processing ndi kudalirika zofunika matabwa mkulu-nyamuka.

2. Mapangidwe a laminated

Mfundo zazikuluzikulu zomwe zimaganiziridwa pakupanga mapangidwe a laminated ndi kukana kutentha, kupirira voteji, kuchuluka kwa guluu kudzazidwa ndi makulidwe a dielectric wosanjikiza, etc. Mfundo zotsatirazi ziyenera kutsatiridwa:

(1) Opanga ma board a prepreg ndi core board ayenera kukhala osasinthasintha.

(2) Pamene kasitomala amafuna mkulu TG pepala, bolodi pachimake ndi prepreg ayenera kugwiritsa ntchito lolingana mkulu TG zakuthupi.

(3) Gawo lamkati lamkati ndi 3OZ kapena pamwamba, ndipo prepreg yokhala ndi utomoni wambiri imasankhidwa.

(4) Ngati kasitomala alibe zofunikira zapadera, kulolerana kwa makulidwe a interlayer dielectric wosanjikiza nthawi zambiri kumayendetsedwa ndi +/- 10%. Kwa mbale ya impedance, kulolerana kwa makulidwe a dielectric kumayendetsedwa ndi IPC-4101 C / M kalasi kulolerana.

3. Kuwongolera kwa interlayer

Kulondola kwa kukula chipukuta misozi ya mkati wosanjikiza pachimake bolodi ndi ulamuliro wa kupanga kukula ayenera molondola kulipidwa kukula likutipatsa aliyense wosanjikiza mkulu-kukwera bolodi kudzera deta anasonkhanitsidwa pa kupanga ndi mbiri deta zinachitikira kwa ena. nthawi yowonetsetsa kukulitsa ndi kutsika kwa bolodi lapakati pagawo lililonse. kusasinthasintha.

4. Mkati wosanjikiza dera luso

Kuti apange matabwa okwera kwambiri, makina ojambulira molunjika a laser (LDI) atha kuyambitsidwa kuti apititse patsogolo luso losanthula zithunzi. Kuti kuwongolera luso la etching la mzere, ndikofunikira kupereka chipukuta misozi m'lifupi mwake ndi pedi mu kapangidwe ka uinjiniya, ndikutsimikizira ngati chipukuta misozi cham'lifupi wosanjikiza mzere, katayanidwe ka mzere, kukula kwa mphete kudzipatula, mzere wodziyimira pawokha, ndipo mtunda wa dzenje ndi mzere ndi wololera, apo ayi sinthani kapangidwe ka engineering.

5. Kukanikiza ndondomeko

Pakalipano, njira zopangira interlayer pamaso pa lamination makamaka zikuphatikizapo: malo anayi (Pin LAM), kusungunuka kotentha, rivet, kusungunula kotentha ndi kuphatikiza kwa rivet. Mapangidwe osiyanasiyana azinthu amatengera njira zosiyanasiyana zoyikira.

6. Kubowola ndondomeko

Chifukwa cha mawonekedwe amtundu uliwonse, mbale ndi mkuwa zimakhala zokhuthala kwambiri, zomwe zimavala kwambiri pobowola ndikuthyola chobowola mosavuta. Chiwerengero cha mabowo, kuthamanga kwa dontho ndi liwiro la kuzungulira ziyenera kusinthidwa moyenera.
