Kungani I-Solder Paste Idinga Ukuthukuthela futhi Igxiliswe?

I-SMT chip processing inezinsiza ezibalulekile ezisekelayo, i-solder paste.

Ukwakheka kwe-solder paste kuqukethe izinhlayiya ze-tin powder alloy kanye ne-flux (i-flux iqukethe i-rosin, i-ejenti esebenzayo, i-solvent, i-thickener, njll.), i-solder paste ifana ne-toothpaste, esetshenziselwa ukunamathisela umshini wokuphrinta we-solder endaweni ye-pcb pad, ukuze umshini wokubeka ukukhweza izingxenye ze-elekthronikhi ezinamathelayo, bese kuthi ukugeleza kabusha ngokuthengisa izinga lokushisa eliphezulu hot melt solder unama bese ulungisa izingxenye ze-elekthronikhi kuphedi.

I-solder inama kungani kufanele ubuyele ekunyakazeni kwezinga lokushisa?

1. Kungani i-solder paste idinga ukufudunyezwa?

I-solder paste ivamise ukugcinwa endaweni yesiqandisi (5-10 degrees Celsius), esiqandisini izokhishwa esikhungweni sendawo yokusebenzela ye-SMT yokungaguquguquki kwezinga lokushisa, uma ivulekele ukusetshenziswa, ngokungahambisani nezinga lokushisa lokuxhumana, ingaphezulu le-solder unama. izonamathela umhwamuko wamanzi, uma ukuze reflow soldering izinga lokushisa eliphezulu, kungase kubonakale ukuqhuma tin, okuholela izinga elibi tin ubuhlalu.Ngakho-ke, i-solder paste ekhishwe esiqandisini ngokuvamile ingcono ukubuyela ekushiseni kwe-2-4H.

2. Kungani i-solder paste kufanele inyakaze?

I-solder paste ibekwe esiqandisini, ngenxa yezingxenye ezihlukene ze-solder paste, ezibekwe isikhathi eside, izingxenye ezihlukahlukene ze-solder paste zizovela into egqinsiwe, ngakho-ke udinga ukugqugquzela (ukugqugquzela ngendlela efanayo 20-30 ukuphenduka. kungaba), uma ingashukunyiswa ngokuqondile, khona-ke izingxenye ezihlukahlukene ze-solder unama azixubekile, azikwazi ukudlala ukusetshenziswa kwe-solder paste ngokwayo.

Isizathu sokuthi kungani i-solder paste kufanele igcinwe esiqandisini esikhundleni sokuthi i-solder paste iqukethe i-solvents kanye ne-rosin, eyokhuphuka uma ibekwe ngokuqondile endaweni evamile, ngaleyo ndlela ibangele ukuba umoya wome.

Kukhona amakhabethe okuphatha unamathisele othomathikhi we-solder emakethe, okuhlanganisa isitoreji, ukufudumeza nokugqugquzela okuzenzakalelayo, njll. Uma inkampani inkulu futhi isebenzisa unamathisele omningi we-solder, ungathenga imishini enjalo yokuphatha nokusebenzisa i-solder paste.

Ukucushwa Okujwayelekile

1. I-Optical Positioning System Enembile

Indlela emine yomthombo wokukhanya iyalungiseka, amandla okukhanya ayalungiseka, ukukhanya kuyafana, futhi ukutholwa kwesithombe kuhle kakhulu.

2. Ukusebenza kahle okuphezulu kanye nesistimu yokuhlanza i-stencil evumelana nezimo

Ipuleti lokusula lerabha elithambile elingagqoki, izindlela zokuhlanza ezomile, ezimanzi kanye ne-vacuum

ukuhlanza kahle, ukuhlakazeka okulula.

3. Intelligent squeegee uhlelo

Isilungiselelo esihlakaniphile esihlelekayo, amamotho amabili aqondile ashayelwa i-squeegee, isistimu yokulawula ingcindezi eyakhelwe ngaphakathi.

4. Okukhethekile PCB ukujiya uhlelo oluguquguqukayo

Ubude beplathifomu bulinganiswa ngokuzenzakalela ngokuya ngokulungiselelwa kogqinsi lwe-PCB, okukhaliphile, okusheshayo, okulula futhi okuthembekile ngesakhiwo.

5. I-Solder Namathisela Ukuhlola Ikhwalithi Yokuphrinta

Umsebenzi we-2D ungabona ngokushesha iziphambeko zokuphrinta, izindawo zokutholwa zingandiswa ngokuzenzakalelayo.

6. I-Axis Servo Drive yokuphrinta

Thuthukisa ibanga lokunemba, unikeze inkundla yokulawula ukuphrinta okuhle, ukuzinza kokusebenza, wandise impilo yesevisi.
