Umzi-mveliso wokwenziwa kwebhodi ye-SMT - Iphepha2

Yintoni ibhodi ye-SMT?

Ibhodi ye-SMT licandelo elibalulekileyo lezixhobo ze-surface Mount technology (SMT), kwaye isetyenziswa ikakhulu ukulawula imisebenzi eyahlukeneyo kunye nokusebenza kwesixhobo.

Zingaphi iindidi zeebhodi zoomatshini be-SMT ezikhoyo?

Iibhodi ze-SMT zivame ukubandakanya iibhodi ze-CPU, iibhodi ze-XMP, iibhodi zokudibanisa i-SYNONET, iibhodi zebhulorho ezijonganayo, njl. Ezi bhodi zixhunywe ngeendlela ezahlukeneyo zokujonga kunye neebhasi kwaye zisebenza kunye ukulawula amacandelo ahlukeneyo omatshini kunye ne-elektroniki yezixhobo ze-SMT.

Umsebenzi ophambili weeBhodi zoomatshini be-SMT

Umsebenzi ophambili kukunyusa ngokuchanekileyo nangokukhawuleza amacandelo ahlukeneyo e-elektroniki kwiindawo ezimiselweyo zeebhodi zeesekethe eziprintiweyo (PCBs). Ngokusebenzisa iintloko eziphakamileyo ezichanekileyo, iinkqubo ezibonakalayo kunye neenkqubo zokulawula ukunyakaza, izixhobo ze-SMT zinokuqinisekisa ukuba indawo yokunyuka, ulwalathiso kunye nokuhlukana kwamacandelo ahlangabezana neemfuno zokuyila.

Uyigcina njani iBhodi yoomatshini be-SMT

Okokuqala, ukuhlolwa rhoqo kunye nokugcinwa sisiseko sokuqinisekisa ukusebenza okuqhelekileyo kwezixhobo ze-SMT. Oku kubandakanya ukuhlolwa kweenkalo ezahlukeneyo ezifana nokucoca, ukuthambisa, ukuqiniswa kunye nokulungelelaniswa kwezixhobo. Ngokuhlola rhoqo, iingxaki ezinokubakho zinokufunyanwa kwaye zisonjululwe ngexesha elifanelekileyo, ngaloo ndlela kuthintelwa impembelelo yokusilela kwesixhobo kwimveliso.

Okwesibini, uqeqesho lobungcali nokusebenza ngundoqo ekuqinisekiseni umgangatho wolondolozo. Ukulungiswa nokugcinwa kwezixhobo ze-SMT kufuneka kugqitywe ngabasebenzi abaqeqeshiweyo abafanele babe nolwazi olufanelekileyo lobugcisa kunye namava asebenzayo, bakwazi ukugweba ngokuchanekileyo imeko yesixhobo kunye nokuthatha amanyathelo ahambelanayo. Ngexesha elifanayo, abaqhubi kufuneka balandele ngokungqongqo iinkqubo zokusebenza ukuphepha umonakalo wesixhobo ngenxa yokusebenza ngokungafanelekanga.

Kwakhona kubaluleke kakhulu ukusebenzisa izixhobo ezifanelekileyo kunye nezixhobo. Xa kulungiswa kwaye kugcinwa izixhobo ze-SMT, izixhobo ezikhethekileyo kunye nezinto ezifana ne-agent yokucoca, i-lubricant, i-fasteners, njl. Ukusebenzisa izixhobo okanye izixhobo ezingafanelekanga kungonakalisa isixhobo kwaye kuchaphazele nokusebenza kwaso.

Ngawaphi amanyathelo okhuseleko kwiibhodi ze-SMT?

Imiba ephambili ekufuneka ithathelwe ingqalelo ngexesha lokuveliswa kweebhodi ze-SMT ibandakanya: ulawulo lomgangatho wecandelo, ukusetwa kwezixhobo kunye nokuphucula, ukulawulwa kwenkqubo ye-welding, ulawulo lokusingqongileyo kunye nokukhuselwa, kunye nolawulo lomgangatho kunye nenkonzo emva kokuthengisa.

Ziziphi iziphumo zokugcinwa ngokungafanelekanga kweebhodi ze-SMT?

Ukugcinwa okungafanelekanga kweebhodi ze-SMT kunokukhokelela kwimiphumo emibi eyahlukeneyo, kubandakanywa iziphene ezidibeneyo ze-solder, i-component offset, i-tombstone phenomenon, njl. Ezi ngxaki ziya kuchaphazela umgangatho kunye nokuthembeka kwe-PCBA.

Kutheni ukhetha ukuba sithenge iibhodi ze-SMT?

1. Iqela lobuchwephesha lobuchwephesha, kunye neqela lokulungisa ibhodi ye-SMT, ibhodi nganye ivavanywa ngezixhobo zobungcali kunye nezixhobo.

2. I-inventri enkulu, inokuqinisekisa ukuhanjiswa kwexesha kunye nenzuzo yexabiso unyaka wonke.

3. Ezinye iibhodi zombini zintsha kwaye zintsha, kwaye zikho nesesibini sesandla sokuqala. Abathengi banokukhetha izixhobo ezifanelekileyo ngokwebhajethi yabo, enceda ukunciphisa iindleko kunye nokwandisa inzuzo.

4. Iqela lobugcisa lisebenza iiyure ezingama-24 ngosuku nobusuku. Naziphi na iingxaki zobugcisa zinokusonjululwa kwi-intanethi, kwaye iinjineli eziphezulu zinokuthunyelwa ukuba zibonelele ngeenkonzo zobugcisa kwisiza.
