Izindinganiso zokuhlola ibhodi le-PCBA nezinyathelo zokuphepha

Izindinganiso zokuhlola ibhodi le-PCBA ibhodi le-PCBA?

I. Izindinganiso zokuhlola ibhodi le-PCB

1. Ukukhubazeka okungathi sína (okuchazwa njenge-CR): noma yikuphi ukukhubazeka okwanele ukubangela ukulimala emzimbeni womuntu noma umshini noma ukubeka engozini ukuphepha kwempilo, njengalokhu: ukungalandeli imithetho yezokuphepha / ukushiswa / ukushaqeka kukagesi.

2. Ukukhubazeka Okukhulu (okubizwa ngokuthi i-MA): Ukukhubazeka okungabangela ukulimala kumkhiqizo, ukusebenza okungavamile, noma kuthinte impilo yesevisi yomkhiqizo ngenxa yezinto ezibonakalayo.

3. Ukukhubazeka okuncane (okuchazwa njenge-MI): akuthinti umsebenzi nempilo yesevisi yomkhiqizo, kukhona ukukhubazeka kwezimonyo kanye nokukhubazeka okuncane noma umehluko ekuhlanganisweni kwendlela.

II.Izimo zokuhlolwa zebhodi le-PCBA

1. ukuze ugweme ukungcoliswa kwezingxenye noma izingxenye, kufanele ukhethe amagilavu ​​noma amagilavu ​​omunwe anokuvikelwa kwe-EOS / ESD, futhi usebenzise indandatho ye-electrostatic.Umthombo wokukhanya yisibani esimhlophe se-fluorescent.Amandla okukhanya kufanele abe ngaphezu kuka-100Lux futhi abonakale ngokucacile phakathi kwamasekhondi angu-10.

2. Indlela yokuhlola: Beka umkhiqizo endaweni eqhele ngamasentimitha angu-40 ukusuka kuwo womabili amehlo, cishe amadigri angu-45 phezulu naphansi, futhi uwuhlole ngokuwubona noma ngengilazi yokukhulisa kathathu.

3. Izinga lokuhlola: (Isampula esekelwe ku-QS9000 C≥0 AQL=0.4% izinga lokusampula; uma amakhasimende enezidingo ezikhethekile, ngokuvumelana nezindinganiso zokwamukela ikhasimende).

4. Uhlelo lwesampula: mil-std-105 E level 2 isampula eyodwa evamile

5. Indlela yokwenza izinqumo: amaphutha amakhulu (CR) AQL 0%

6. Ububi obukhulu(MA)AQL 0.4%

7. I-Secondary Inferiority(MI)-AQL-0.65%

Njengoba abanye usayizi webhodi le-PCB lincane, ngokuvamile lisebenzisa indlela yokuhlanganisa, lapho kuqedwa ukucutshungulwa komhlangano we-PCBA, kuyadingeka ukuhlukanisa iphazili ye-PCBA.Ukwehlukanisa kuhlukaniswe ngokuyinhloko kube i-sub-paneling kanye ne-sub-paneling yomshini, inqubo yokufaka amaphaneli, kufanele inake ezinye izinyathelo zokuvimbela ukulimala kwebhodi eliphelele le-PCBA.

I. izimfuneko zephaneli elincane lezandla

Lapho ugoqa unqenqema lwebhodi, kufanele usebenzise izandla zombili ukuze ubambe unqenqema oluphansi lwebhodi le-PCB, kude ne-V usike ngaphansi kuka-20 mm ukuze ugweme ukugoba nokuguqulwa.

II.Izidingo zebhodi lokuhlukanisa umshini

1. Iphoyinti lokusekela elizinzile

Uma kungekho ukusekelwa, ukucindezeleka okubangelwayo kungalimaza i-substrate namajoyini e-solder.Ukuhlanekezela ibhodi, noma ukusebenzisa ingcindezi engxenyeni phakathi nenqubo yokuhlukanisa, kungase kubangele amaphutha afihliwe noma asobala.

2. Gqoka amathuluzi okuzivikela

Ngaphambi kokusebenza, kufanele kulungiselelwe ukuvikeleka, kudingeka kufake idivayisi yokukhanyisa evikela amehlo enemvamisa ephezulu ukuvikela ukuphepha komsebenzisi.Kungcono futhi ukuletha ingilazi ukuvikela amehlo.

3. kufanele basebenzise utshwala ngokuvamile ukuze basule ithuluzi lokuphotha lomshini kanye nethuluzi lokususa uthuli lwe-PCB olukhiqizwa inqubo yesihlukanisi, ukuze kugcinwe ukusebenza okuvamile kwesihlukanisi.

4. Ngemuva kwenombolo ethile yezikhathi zokusetshenziswa, udinga ukushelela isilayidi nama-bearings we-distributor futhi uhlole ukuthi izikulufi zikhululekile, njll.

5. ohlelweni lokusebenzisa umshini, ingaphezulu letafula kufanele ligcinwe lihlanzekile, kungcono kakhulu ukuthi ungabeki ezinye izinto, ukuze ugweme ukulimala kwethuluzi kanye nezinto ngenxa yokuwa kwezinto ezisethuluzini. .Nakuba kukhona amehlo kagesi okugcinwa, kodwa ekusetshenzisweni, qaphela iminwe kanye namathuluzi okuhambisana nesikhathi esithile sokuphepha.
Ngokuvamile, uma usebenzisa izihlukanisi ze-PCBA, izihlukanisi zomshini zisebenza kahle kakhulu futhi zinezinga eliphansi lomonakalo kunezihlukanisi ezenziwa ngesandla.Kodwa-ke, lapho kwenziwa ukuhlukaniswa komshini, kuyadingeka futhi ukusebenza ngokuhambisana nenqubo yokunciphisa iphutha lomuntu.

I-Zhejiang NeoDen Technology Co., LTD., eyasungulwa ngo-2010, ingumkhiqizi ochwepheshe okhethekile emshinini wokukhetha nendawo we-SMT, ihhavini eligeleza kabusha, umshini wokuphrinta we-stencil, ulayini wokukhiqiza we-SMT neminye Imikhiqizo ye-SMT.Sineqembu lethu le-R & D kanye nemboni yethu, sisebenzisa i-R&D yethu ecebile enokuhlangenwe nakho, ukukhiqizwa okuqeqeshwe kahle, sazuza idumela elihle kumakhasimende omhlaba wonke.

Sikholelwa ukuthi abantu abakhulu nozakwethu benza i-NeoDen inkampani enhle futhi ukuzibophezela kwethu Ekusunguleni, Ukuhlukahluka kanye Nokusimama kuqinisekisa ukuthi i-SMT automation ifinyeleleka kuwo wonke umuntu wokuzilibazisa kuyo yonke indawo.
