I-Hand Soldering FPC Boards: Amathiphu Abalulekile Nokucatshangelwa

Ngenisa

Lapho kuhlanganiswa amabhodi e-flexible printed circuit (FPC), ukufaka isandla ngesandla kuyindlela esetshenziswa kakhulu ngenxa yokunemba kwayo nokusebenza kahle kwezindleko. Kodwa-ke, kunezici ezimbalwa ezibalulekile okufanele uzicabangele ukuze uzuze ukuxhumana okuphumelelayo kwe-solder.Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngamaphuzu abalulekile okufanele anakwe lapho e-soldering amabhodi wesifunda se-FPC, okuhlanganisa indlela yokuxhumana phakathi kwephuzu lensimbi ye-soldering kanye nengxenye, indlela yokuhlinzeka yocingo lokunamathisela, isikhathi sokushisa kanye nezinga lokushisa. izilungiselelo, njll Njengesixwayiso esibalulekile sokuqinisekisa inqubo yokushisela engenasici. Ake sicwilise!

1. Indlela yokuxhumana phakathi kwethiphu yensimbi yokunamathisela kanye nezingxenye ezimbili ezizoshiselwa

Ukufeza ukuxhumana okuqinile phakathi kwensimbi yokunamathisela kanye nengxenye kubalulekile ekuphumeleleni kwenqubo yokuhlanganisa. Sicela unakisise amaphuzu alandelayo:

I. Gcina ithiphu yensimbi yokunamathisela ihlanzekile futhi ifakwe ithini:Ngaphambi kokuqala inqubo yokuhlanganisa, qiniseka ukuthi ithiphu le-soldering iron lihlanzekile futhi lifakwe ithini ngendlela efanele. Lokhu kuqinisekisa ukudluliswa kokushisa okungcono futhi kuvimbela i-oxidation, okuholela ekuhlanganiseni kwe-solder ebushelelezi.

2. Faka i-engeli engakwesokudla:gcina i-engeli efanelekile phakathi kwethiphu yensimbi ehlanganisiwe nebhodi le-FPC. Ngokufanelekile, i-engeli enconyiwe iphakathi kuka-30 no-45 degrees. Lokhu kukhuthaza ukudluliswa kokushisa okufanele futhi kuvimbele ukushisa ngokweqile noma izingxenye ezilimazayo.

3. Faka ingcindezi eyanele:Faka ingcindezi encane engxenyeni ezodayiswa, kuyilapho uqinisekisa ukuthi awusebenzisi amandla amaningi njengoba lokhu kungase kubangele umonakalo. Lokhu kusiza ukuqinisekisa ukuxhumana okulungile nokuzinzile phakathi kwethiphu yensimbi ehlanganisiwe nebhodi le-FPC.

2. Indlela yokuhlinzeka ngezintambo zokushisela

Indlela intambo yokushisela ehlinzekwa ngayo idlala indima ebalulekile ekuzuzeni uxhumano olunembayo lwe-welding. Sicela ulandele le mihlahlandlela:

I. Sebenzisa inani elilungile le-solder:Gwema ukusebenzisa i-solder kakhulu ngoba kungabangela ukuvala ibhuloho noma ukufinyela. Ngakolunye uhlangothi, i-solder enganele ingase ibangele uxhumano olubi. Ngakho-ke, inani elifanele kufanele lisetshenziswe ngokusekelwe ubukhulu kanye yinkimbinkimbi ye-solder joint.

2. Khetha ucingo lwekhwalithi ephezulu:Ngaso sonke isikhathi sebenzisa izintambo zekhwalithi ephezulu ezifanele ukushisela ibhodi lesekethe ye-FPC. Izinga le-solder wire lithinta kakhulu umphumela we-solder jikelele.

3. Faka intambo yokushisela ngakolunye uhlangothi:Ukuqinisekisa ukudluliswa kokushisa okulungile, sicela ufake intambo yokushisela kusukela kolunye uhlangothi lwejoyinti le-solder. Lobu buchwepheshe buvumela i-solder ukuthi igeleze ngokukhululekile futhi yakha isibopho esiqinile phakathi kwezingxenye.

3. Isikhathi sokushisela kanye nezilungiselelo zokushisa

Isikhathi esinembile sokudambisa kanye nezilungiselelo zokushisa zibalulekile ekuzuzeni ukuxhumeka okuthembekile kwe-soldering. Cabangela izici ezilandelayo:

I. Thola izinga lokushisa elilungile:Zijwayeze nebanga lokushisa elinconyiwe lokunamathisela amabhodi e-FPC. Ngokuvamile, amazinga okushisa aphakathi kuka-250 no-300 degrees Celsius afanelekile. Kodwa-ke, kubalulekile ukulandela imihlahlandlela ethile enikezwe umenzi ukuvimbela ukulimala ezingxenyeni ezibucayi.

2. Lawula kahle isikhathi sokushisisa:isikhathi sokushisa asikwazi ukuba sifushane kakhulu noma side kakhulu. Ukushisa isikhathi eside kungabangela ukulimala kwengxenye, kuyilapho ukushisa okunganele kungabangela amalunga abuthakathaka e-solder. Khomba ibhalansi ehamba phambili ngokunamathela ezikhathini zokushisisa ezishiwo.

4. Izinyathelo zokuphepha zokushisela

Ukuze ugweme izinkinga ezingase zibe khona ngesikhathi sokushisela, kufanele kuthathwe izinyathelo zokuphepha ezidingekayo. Faka imihlahlandlela elandelayo:

I. Qinisekisa ukungena komoya owanele:Sebenza endaweni enomoya omuhle ukuze uvimbele ukuphefumula ezintweni eziyingozi ezikhishwa ngesikhathi senqubo yokushisela.

2. Sebenzisa izixwayiso ze-ESD:Amabhodi esekethe e-FPC angenwa kalula yi-electrostatic discharge (ESD). Sebenzisa omata bokuvikela be-ESD, amabhande esihlakaleni, nezinye izinyathelo ezifanele ukuze ugweme umonakalo odalwe i-ESD.

3. Gwema ukushisa ngokweqile:Ungashisi ngokweqile izingxenye noma izindawo ezithile ngesikhathi sokushisela, ngaphandle kwalokho kungavela umonakalo. Gcina indlela ezinzile futhi elawulwayo ukuze uvimbele izinkinga ezihlobene nokushisa ngokweqile.

Ekuphetheni

Lapho usebenza namabhodi esekethe e-FPC, amasu afanele okusonda ngesandla abalulekile ukuze kuqinisekiswe ukuxhumana okuthembekile nokuqinile. Ngokunaka kakhulu izindlela zokuxhumana, izinsiza zocingo, isikhathi nezilungiselelo zokushisa, nokunamathela ezinyathelweni ezidingekayo, ungafinyelela imiphumela ephumelelayo yokushisela. Ngokuzijwayeza nokunaka imininingwane, ungaba yingcweti yaleli khono elibalulekile ekwenzeni izinto zikagesi, okuholela kumabhodi e-FPC asezingeni eliphezulu, asebenzayo.
