4-Layer PCB Stackups Kubowola Kulondola ndi Ubwino Wapa Khoma : Malangizo a Katswiri a Capel

Tsegulani:

Mukamapanga matabwa osindikizira (PCBs), kuonetsetsa kuti kubowola molondola komanso mtundu wa khoma la dzenje muzitsulo za 4-wosanjikiza za PCB ndizofunikira kwambiri pakugwira ntchito ndi kudalirika kwa chipangizo chamagetsi.Capel ndi kampani yotsogola yokhala ndi zaka 15 mumakampani a PCB, yoyang'anira bwino kwambiri ngati cholinga chake chachikulu.Blog iyi ikufuna kukupatsirani zidziwitso zofunikira za momwe mungakwaniritsire kubowola kolondola komanso mtundu wakhoma la dzenje mu 4-layer PCB stack-up, ndikuwunikiranso ukatswiri wa Capel ndi mayankho odalirika a PCB.

1. Kufunika kwa kubowola molondola ndi mtundu wa khoma la dzenje mu 4-wosanjikiza PCB:

Kubowola kolondola komanso mtundu wa khoma la dzenje ndizinthu zazikulu zomwe zimakhudza mwachindunji magwiridwe antchito a 4-wosanjikiza PCB. Kubowola kosalongosoka kungayambitse kusalinganika kwa zigawo, zovuta za impedance, ndi nkhani za kukhulupirika. Momwemonso, kusakwanira kwa khoma la mabowo kumatha kukhudza magwiridwe antchito olumikizirana ndi dzenje (PTH), kubweretsa kudalirika komanso kuchepa kwamagetsi.

2. Sankhani zida zoyenera kubowola ndi ukadaulo:

Kuti muwonetsetse kuti pobowola molondola, yikani ndalama pazida zobowola zapamwamba kwambiri zomwe zimalola kuwongolera mwachangu liwiro, kuya, ndi kuyanika. Makina obowola okha omwe ali ndi zida zapamwamba monga kubowola mothandizidwa ndi laser komanso kuwongolera koyendetsedwa ndi makompyuta amalimbikitsidwa kwambiri. Kuphatikiza apo, lingalirani ma microvias obowoleredwa ndi laser pama board apamwamba ambiri popeza amapereka kulondola komanso kudalirika.

3. Kapangidwe kabwino ka stacking:

Kukonzekera koyenera kosungirako kumagwira ntchito yofunika kwambiri pakubowola bwino komanso kukhazikika kwa khoma. Chonde ganizirani malangizo awa:
- Chepetsani kuchuluka kwa magawo azizindikiro kuti muchepetse zovuta kubowola.
- Sungani yunifolomu ya makulidwe apakati kuti mabowo akubowola asapendekeke.
- Gwiritsani ntchito kugawa mkuwa moyenera kuti mupewe kupindika ndi kupindika pobowola.
- Ikani zizindikiro zothamanga kwambiri ndi zigawo zowonongeka kutali ndi malo obowoledwa kuti muchepetse chiopsezo cha kusokoneza magetsi.

4. Njira yopangira PCB yolondola:

Capel ali ndi zaka zambiri za 15 ndipo amatsatira njira zokhwima zopangira kuti awonetsetse kuti kubowola kuli kolondola komanso makoma a dzenje lapamwamba mu 4-layer PCB stack-ups. Pokhala ndi zida zamakono komanso anthu aluso, amagwiritsa ntchito umisiri wapamwamba kwambiri monga Laser Direct Imaging (LDI) ndi Automated Optical Inspection (AOI) kuti azitha kuyang'ana bwino komanso kuyang'ana bwino panthawi yopanga. ukatswiri izi zimatsimikizira odalirika, wangwiro PCBs makasitomala.

5. Njira zowongolera bwino kwambiri:

Kudzipereka kwa Capel pakuwongolera kwaubwino kumawonekera m'njira zake zowunika mozama. Amagwiritsa ntchito njira zoyesera zapamwamba, kuphatikiza kuyesa magetsi, kuyesa kudalirika komanso kuyesa kukalamba kwamafuta. Kupyolera mu kuyang'anira nthawi yeniyeni ndi kutsata miyezo yapadziko lonse, Capel amaonetsetsa kuti PCB iliyonse yomwe amapanga ikukwaniritsa kapena kupitirira zomwe makasitomala amayembekezera.

6. Ntchito zoyeserera za PCB za Capel ndi misonkhano:

Monga wopereka mayankho a PCB oyimitsa kamodzi, Capel sikuti amangokhazikika pakupanga ma PCB osanjikiza 4, komanso amapereka ma prototyping ofulumira a PCB komanso ntchito zochitira msonkhano wa SMT PCB. Njira yowongokayi imathetsa kufunikira kwa ogulitsa angapo ndikuwonetsetsa kusakanikirana kosasunthika kwa magawo onse a PCB kupanga, potero kupulumutsa nthawi ndikuchepetsa mtengo kwa makasitomala ake ofunikira.

Pomaliza:

Zikafika pakukwaniritsa kubowola molondola komanso mtundu wa khoma la dzenje mu 4-wosanjikiza PCB, kugwira ntchito ndi wodziwa komanso wodalirika wopanga PCB ngati Capel ndikofunikira.Capel ndiwodziwika bwino pamsika ndikugogomezera kuwongolera kwaukadaulo, ukadaulo wapamwamba komanso mayankho athunthu a PCB. Mwa kuika patsogolo kulondola kwa kubowola ndi khalidwe la khoma la dzenje, mukhoza kuonetsetsa kuti zipangizo zanu zamagetsi zimagwira ntchito bwino komanso zimakhala ndi moyo wautali.
