Mubikorwa byo gutunganya chip ya SMT,umuzunguruko mugufini ibintu bisanzwe bitunganijwe neza.Ikibaho kigufi cya PCBA cyumuzunguruko ntigishobora gukoreshwa mubisanzwe.Ibikurikira nuburyo busanzwe bwo kugenzura kumuzingo mugufi wubuyobozi bwa PCBA.

1. Birasabwa gukoresha isesengura rigufi ryumwanya wo gusesengura kugirango umenye imiterere mibi.

2. Mugihe habaye umubare munini wumuzunguruko mugufi, birasabwa gufata ikibaho cyumuzunguruko kugirango ugabanye insinga, hanyuma imbaraga kuri buri gace kugirango ugenzure uduce dufite imiyoboro migufi umwe umwe.

3. Birasabwa gukoresha multimeter kugirango umenye niba urufunguzo rwumuzunguruko rugufi.Igihe cyose patch ya SMT irangiye, IC ikeneye gukoresha multimeter kugirango imenye niba amashanyarazi nubutaka bigenda byizunguruka.

4. Menyesha umuyoboro mugufi wumuzunguruko ku gishushanyo cya PCB, reba umwanya uri ku kibaho cy’umuzunguruko aho bishoboka cyane ko umuzunguruko mugufi ushobora kubaho, kandi witondere niba hari umuyoboro mugufi imbere muri IC.

5. Witondere gusudira witonze ibyo bice bito bya capacitif, bitabaye ibyo umuzunguruko mugufi hagati yumuriro nubutaka birashoboka cyane.

6. Niba hari chip ya BGA, kubera ko igice kinini cyabagurisha gitwikiriwe na chip kandi ntibyoroshye kubona, kandi ni imbaho ​​zumuzunguruko, birasabwa guhagarika amashanyarazi ya buri chip mugikorwa cyo gushushanya. , hanyuma ubahuze namasaro ya magneti cyangwa 0 ohm irwanya.Mugihe cyumuzunguruko mugufi, guhagarika magnetiki yamashanyarazi bizoroha kubona chip kurubaho.
