Kuchokera ku Malingaliro a Zamalonda: Opanga ma PCB angapereke zitsanzo za malonda kwaulere. Makasitomala amatha kukonza maulendo opita ku fakitale kapena kupeza zitsanzo kuchokera ku kampani. Mwa kuyang'ana zitsanzozo kapena kufunsa munthu wodziwa bwino za ma PCB, akhoza kuyamba...

Chifukwa cha kukwera kwa mizinda mosalekeza, kukula ndi kuchuluka kwa anthu m'mizinda kukuchulukirachulukira, ndipo mizinda ikukumana ndi mavuto ndi ziwopsezo zambiri zokhudzana ndi chitetezo. Machitidwe achitetezo achikhalidwe amafuna anthu ambiri ogwira ntchito komanso othandizana nawo...

Njira yopangira PCB imaphatikizapo magawo angapo ofunikira, kuyambira pakutsimikizira deta yopangira bolodi yoperekedwa ndi ogulitsa, kuphatikiza kudula zinthu, kuboola, kumiza mkuwa ndi mankhwala, kusamutsa zithunzi, kuyika zithunzi, kuchotsa filimu, kupukuta, kugwiritsa ntchito chigoba cha solder, kusindikiza silkscreen, kuphimba zala zagolide, kupanga, ndi kuyesa komaliza. Gawo lililonse limachitidwa mosamala malinga ndi zofunikira za ndondomeko kuti zitsimikizire mtundu ndi kulondola kwa ma board a circuit. Kudzera mu masitepe awa, opanga PCB amatha kupanga ma board a circuit osindikizidwa apamwamba komanso ogwira ntchito mokwanira kuti akwaniritse zofunikira zosiyanasiyana zamagetsi.

Chifukwa cha kupita patsogolo kwa ukadaulo wolumikizirana opanda zingwe, kufunika kwa ma chip olumikizirana opanda zingwe monga gawo lalikulu la machitidwe olumikizirana opanda zingwe kukukulirakulira. Ma chip olumikizirana opanda zingwe achikhalidwe nthawi zambiri amakhala ndi...

M'dziko lamakono lomwe likukula mofulumira, ma satellite intelligent terminal security chips atuluka, cholinga chake ndi kuthetsa mavuto achitetezo kudzera mu mfundo zatsopano. Ndi chitukuko chopitilira cha ukadaulo wa netiweki, mavuto achitetezo cha netiweki akuchulukirachulukira...

Gold Finger PCB ndi mtundu wapadera wa bolodi losindikizidwa, lomwe limagwiritsidwa ntchito kwambiri m'mapulogalamu omwe amafunikira kudalirika kwambiri komanso kusawonongeka, monga ma motherboard apakompyuta, makadi ojambula zithunzi ndi zida zina zamagetsi. Nkhaniyi ifotokoza tanthauzo...

IPC yakhazikitsa muyezo woyesera chigoba cha solder ngati chitsogozo cha makampani opanga zinthu, OEMs, ndi opanga PCB. IPC SM-840D imagawa zigawo za chigoba cha solder, Class T ndi Class H, mwachidule motere: T-Telecommunications: kuphatikiza makompyuta, te...

Kuyerekeza kusiyana pakati pa miyezo ya IPC2 ndi IPC3 ya ma PCB a magalimoto: Mlingo wa IPC umawonetsa mulingo wa mtundu uliwonse wa bolodi losindikizidwa, ndipo opanga ena amagetsi ali ndi mphamvu yopangira IPC yoyamba ndi yachiwiri yokha...

Miyezo Yoyendera ya X-RAY 1. Malumikizidwe a solder a BGA alibe choletsa: Zofunikira pakuweruza: ndizovomerezeka pamene choletsa chili chochepera theka la kuzungulira kwa solder pad; Pamene choletsa chili chachikulu kuposa kapena chofanana ndi theka la kuzungulira kwa solder pad, ...

HDI (High Density Interconnection) ndi bolodi laling'ono lopangidwira ogwiritsa ntchito voliyumu yochepa. Poyerekeza ndi ma PCB wamba, chinthu chofunikira kwambiri cha HDI ndi kuchuluka kwa mawaya ake. Kusiyana pakati pa ziwirizi kumawonekera makamaka m'magawo anayi otsatirawa...
