1. Izingxenye ezijwayelekile kufanele zinake ukubekezelela usayizi wezingxenye zabakhiqizi abahlukene, izingxenye ezingajwayelekile kufanele ziklanywe ngokuhambisana nosayizi wangempela wezingxenye zemifanekiso yephedi kanye nesikhala sephedi.
2. Umklamo wesifunda sokuthembeka okuphezulu kufanele unwetshwe ukucubungula ipuleti le-solder, ububanzi bephedi = 1.1 kuya ku-1.2 izikhathi ububanzi bezingxenye zokuphela kwe-solder.
3. Idizayini ephezulu kakhulu kumtapo wolwazi wesoftware wezingxenye ukulungisa usayizi wephedi.
4. Ibanga phakathi kwezingxenye ezihlukahlukene, izintambo, amaphuzu okuhlola, i- through-hole, ama-pads kanye noxhumo lwezintambo, ukumelana ne-solder, njll. kufanele kuklanywe ngokuhambisana nezinqubo ezahlukene.
5. Cabanga ngokusebenza kabusha.
6. Cabangela ukunqanyulwa kokushisa, imvamisa ephezulu, ukuphazamiseka kwe-anti-electromagnetic nezinye izinkinga.
7. ukubekwa kwezingxenye kanye nokuqondisa kufanele kuklanywe ngokuhambisana nezidingo zokugeleza kabusha noma inqubo ye-wave soldering.Isibonelo, uma usebenzisa inqubo yokuphinda kufakwe i-reflow soldering, isiqondiso sesakhiwo sezingxenye sokucabangela isiqondiso se-PCB kuhhavini lokugeleza kabusha.Uma usebenzisa umshini we-wave soldering, indawo yomshini ayikwazi ukubekwa i-PLCC, i-FP, izixhumi nezingxenye ezinkulu ze-SOIC;ukuze kuncishiswe umphumela wethunzi le-wave, uthuthukise ikhwalithi ye-welding, ukuhlelwa kwezingxenye ezihlukahlukene kanye nendawo yezidingo ezikhethekile;i-wave soldering pad graphic design, izingxenye eziwunxande, i-SOT, ubude bephedi yezingxenye ze-SOP kufanele inwetshwe ukuze kubhekwane namapheya amabili angaphandle e-SOP Abanzi amaphedi e-solder ukuze kukhangiswe i-solder eyeqile, engaphansi kuka-3.2mm × 1.6mm izingxenye eziwunxande, zingashintshwa ngazo zombili. imiphetho pad 45 ° processing, nokunye.
8. Idizayini yebhodi lesifunda ephrintiwe nayo icubungula imishini.Isakhiwo esihlukile somshini wokupakisha, ukuqondanisa, ukudluliswa kwebhodi lesifunda eliphrintiwe kuhlukile, ngakho-ke ukuma kwendawo yembobo yebhodi lesifunda ephrintiwe, ihluzo zophawu lokuma (Mark) nendawo, umumo wonqenqema webhodi lesifunda, kanye nomphetho webhodi lesifunda eliphrintiwe eduze. indawo yezingxenye ayikwazi ukubekwa inezidingo ezahlukene.Uma inqubo ye-wave soldering isetshenziswa, kuyadingeka futhi ukucabangela unqenqema lwenqubo yochungechunge lokudlulisa ibhodi lesifunda eliphrintiwe lidinga ukushiywa.
9. Kodwa futhi cabangela imibhalo ehambisanayo yokuklama.
10. ukunciphisa izindleko zokukhiqiza ngaphansi kwesisekelo sokuqinisekisa ukwethembeka.
11. umklamo ofanayo webhodi lesifunda eliphrintiwe, ukusetshenziswa kwamayunithi kufanele kuhambisane.
12. Umhlangano ohlangene kabili kanye nomhlangano owodwa ohlangothini olulodwa lwezidingo zokuklama ibhodi lesifunda eliphrintiwe kuyafana
13. Kodwa futhi cabangela imibhalo ehambisanayo yokuklama.
