Ulwazi lwe-SMT

Ithuthukisa ukusebenza kahle kwe-SMT ngo-25%+, i-Rich Full Joy isebenzisa i-YAMAHA YSM10 ukuze ithole ukunemba okungu-±0.035mm ekukhiqizweni kwe-PCBA, iqinisekisa ukulethwa okusheshayo nokuthembekile.

Thola ukuthi i-RICH FULL JOY's AX7900 Micro-focus X-RAY Fluoroscopy Inspection Equipment iqinisekisa kanjani ikhwalithi ye-PCBA engenaphutha ekukhiqizweni kwe-SMT. Inikeza izithombe ezicacile, ukuhlolwa kwesikhathi sangempela, kanye nokutholwa kweziphambeko okuthuthukisiwe, iphakamisa umugqa wakho wokukhiqiza ezindinganisweni ezintsha.

Ukuhambisana kwe-Electromagnetic (EMC) kuyisici esibalulekile sokuklama nokuhlanganisa ama-PCB, ikakhulukazi ekuhlanganisweni kwe-PCB ye-SMT (Surface-Mount Technology). Njengoba amadivayisi eba mancane futhi eshesha, ukugcina amazinga okusebenza okuphezulu ngenkathi kuvimbela ukuphazamiseka kwe-electromagnetic (EMI) kubalulekile ekusebenzeni okuthembekile. Lesi sihloko sigxila emaphuzu abalulekile okuklama i-EMC ekuhlanganisweni kwe-PCB ye-SMT, sigxile emasu abalulekile asiza ekunciphiseni i-EMI nokuqinisekisa ukuthembeka kwe-PCB.

Emkhakheni ohlala ushintsha wokukhiqiza izinto zikagesi, amabhodi wesekethe aphrintiwe ngendlela eguquguqukayo (ama-flex PCB)sezibe yitshe lesisekelo lomklamo omusha kanye nokuhlanganiswa kwamadivayisi amancane. Njengoba kunesidingo esikhulu sama-elekthronikhi alula, aqinile, futhi okusindisa isikhala, ukuhlanganiswa kwama-PCB aguquguqukayo ku Ukuhlanganiswa kwe-PCB ye-Surface Mount Technology (SMT)ivule amathuba amasha ekwakhiweni kwemikhiqizo yesimanje.

Ubuchwepheshe Bokukhweza I-Surface (SMT) bushintshe kakhulu ukukhiqizwa kwe-PCB ngokuvumela okuxinene kakhulu, okushesha kakhulu, futhi okungabizi kakhuluukukhiqizwa. Kodwa-ke, ngenxa yobunzima benqubo, amaphutha angavela ku- izigaba ezahlukahlukene, okuthinta amazinga okukhiqiza, ukuthembeka, kanye nokusebenza.

Ezweni le- Umhlangano we-PCB we-SMT (Ubuchwepheshe Bokumisa Okungaphezulu), ukufinyelela ikhwalithi ephezulu, imikhiqizo ye-elekthronikhi ethembekilekudinga okungaphezu nje kokubekwa ngokunembile kanye nokushiselwa. Isici esibalulekile esivame ukunganakwa kodwa esingenza noma siphule ubuqotho be- ibhodi lesifunda eliphrintiwe (i-PCB)kuyinto Ukukhishwa Kwe-Electrostatic (ESD).

Ezweni le- Umhlangano we-PCB we-SMT (Surface Mount Technology), ukugcina uhlu oluthembekile lwezingxenye ze-elekthronikhi kanye nokwenza ngcono uchungechunge lokuhlinzeka kubalulekile ekuqinisekiseni ukukhiqizwa okubushelelezi, ukunciphisa izindleko, kanye nokuhlangabezana nezikhathi zokulethwa eziqinile. Lesi sihloko sihlola imikhuba emihle kakhulu ukuphathwa kwempahla yezingxenye ze-elekthronikhifuthi ukwenza ngcono uchungechunge lokuhlinzekwa kwempahla, eyenzelwe ngqo izindawo zokukhiqiza ze-PCB ezinezingqimba eziningi, i-RF, kanye nezindawo eziyinkimbinkimbi zokukhiqiza i-PCB.

Thola umehluko phakathi kwensizakalo eyodwa ye-PCBA kanye namamodeli okukhiqiza endabuko. Funda ukuthi ukubambisana kokuklama, ukuthengwa okuhlanganisiwe, kanye nokusebenza kahle kokukhiqiza kuguqula kanjani ikusasa lokukhiqiza izinto zikagesi.

Ukuqonda Ukuhlolwa kwe-SPI: Isihluthulelo Sokukhiqiza Izinto Ze-elekthronikhi Ezithembekile Emkhakheni wokukhiqiza izinto ze-elekthronikhi, ukunemba nokuthembeka kubaluleke kakhulu. Ubuchwepheshe Bokukhweza I-Surface (SMT) buguqule imboni, okwenza kube lula ukukhiqizwa kwe-compact a...
