PCBA ibhodi imigangatho yokuhlola kunye nezilumkiso

PCBA ibhodi PCBA ibhodi ukuhlolwa imigangatho?

I. Imigangatho yokuhlolwa kwebhodi yePCB

1. Iziphene ezimandundu (ezichazwa njengeCR): naziphi na iziphene ezaneleyo ezinokubangela ukwenzakala emzimbeni womntu okanye kumatshini okanye ukubeka emngciphekweni ukhuseleko lobomi, njengale: ukungathotyelwa kwemigaqo yokhuseleko / ukutshisa / ukothuka kombane.

2. Iziphene ezinkulu (ezichazwe njenge-MA): Iziphene ezinokubangela umonakalo kwimveliso, ukusebenza okungaqhelekanga, okanye ukuchaphazela ubomi benkonzo yemveliso ngenxa yezinto eziphathekayo.

3. Iziphene ezincinci (ezichazwe njenge-MI): azichaphazeli umsebenzi kunye nobomi benkonzo yemveliso, kukho iziphene ze-cosmetic kunye neziphene ezincinci okanye ukungafani kwindibano yendlela.

II.Imiqathango yokuhlolwa kwebhodi PCBA

1. ukwenzela ukuthintela ukungcoliseka kwamacandelo okanye iinxalenye, kufuneka ukhethe iiglavu okanye iiglavu zeminwe kunye nokhuseleko lwe-EOS / ESD, kwaye usebenzise i-electrostatic ring operation.Umthombo wokukhanya sisibane esimhlophe se-fluorescent.Ukukhanya kokukhanya kufuneka kube ngaphezulu kwe-100Lux kwaye kubonakale ngokucacileyo kwimizuzwana eyi-10.

2. Indlela yokuhlola: Beka imveliso malunga ne-40 cm kude namehlo omabini, malunga ne-45 degrees phezulu nangaphantsi, kwaye uyihlole ngokubonakalayo okanye ngeglasi yokukhulisa kathathu.

3. Umgangatho wokuhlola: (Iisampulu esekelwe kwi-QS9000 C≥0 AQL = i-0.4% inqanaba lesampula; ukuba abathengi baneemfuno ezizodwa, ngokwemigangatho yokwamkelwa kwabathengi).

4. Isicwangciso sesampulu: mil-std-105 E inqanaba 2 eqhelekileyo isampulu eyodwa

5. Iikhrayitheriya zokwenza izigqibo: iziphene ezinzulu (CR) AQL 0%

6. Ukusilela okukhulu(MA)AQL 0.4%

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

Njengoko ezinye PCB ibhodi ubukhulu incinane ngokwentelekiso, ngokufuthi usebenzisa indlela splicing, ekugqityweni ukusetyenzwa kwendibano PCBA, kuyimfuneko ukwahlula iphazili PCBA.Ukwahlula ubukhulu becala yahlulwe kwi-sub-paneling ye-manual kunye ne-sub-paneling yomatshini, kwinkqubo ye-sub-paneling, kufuneka ithathele ingqalelo kwezinye izilumkiso zokuthintela umonakalo kwibhodi ye-PCBA epheleleyo.

I. iimfuno zephaneli ephantsi yesandla

Xa usonga udini lwebhodi, kufuneka usebenzise izandla zozibini ukubamba umgca ongezantsi webhodi ye-PCB, kude ne-V cut ngaphantsi kwe-20 mm ukuphepha ukugoba kunye nokuguqulwa.

II.Iimfuno zebhodi yokwahlula umatshini

1. Indawo yenkxaso ezinzileyo

Ukuba akukho nkxaso, uxinzelelo olubangelwayo lungonakalisa i-substrate kunye ne-solder joints.Ukuphazamisa ibhodi, okanye ukusebenzisa uxinzelelo kwicandelo ngexesha lenkqubo yokuhlukanisa, kunokubangela iziphene ezifihlakeleyo okanye ezicacileyo.

2. Nxiba izixhobo zokukhusela

Ngaphambi kokusebenza, kufuneka ulungiselele ukhuseleko, kufuneka ufakele isixhobo sokukhanyisa iliso esikwisantya esiphezulu ukukhusela ukhuseleko lomsebenzisi.Kungcono ukuba uze nepere yeglasi ukukhusela amehlo.

3. kufuneka basebenzise utywala rhoqo ukucima isixhobo sokuphotha somatshini kunye nesixhobo sokuphelisa uthuli lwe-PCB oluveliswe kwinkqubo yokuqhekeka, ukugcina ukusebenza okuqhelekileyo kwesahluli.

4. Emva kwenani elithile lamaxesha okusetyenziswa, kufuneka ululaze isilayidi kunye neebheringi ze-distributor kwaye ukhangele ukuba i-screws ikhululekile, njl.

5. kwinkqubo yokusebenzisa umatshini, umphezulu wetafile kufuneka ugcinwe ucocekile, kungcono ukuba ungabeki ezinye izinto, ukwenzela ukuba ugweme umonakalo kwisixhobo kunye nezinto ngenxa yezinto ezikwisixhobo esiwayo. .Nangona kukho amehlo ombane okugcinwa, kodwa kwinkqubo yokusetyenziswa, nikela ingqalelo kwiminwe kunye nezixhobo zokubambelela kwixesha elithile lokhuseleko.
Ngokubanzi, xa usebenzisa ii-splitters ze-PCBA, ii-splitters zoomatshini zisebenza kakuhle kwaye zinezinga eliphantsi lomonakalo kune-splitter manual.Nangona kunjalo, xa usenza ukwahlula umatshini, kuyafuneka ukuba usebenze ngokuhambelana nenkqubo yokunciphisa impazamo yomntu.

I-Zhejiang NeoDen Technology Co., LTD., Yasekwa ngo-2010, ngumvelisi oqeqeshiweyo okhethekileyo kwi-SMT pick and place machine, i-oven reflow, umatshini wokushicilela we-stencil, umgca wemveliso we-SMT kunye nezinye iiMveliso ze-SMT.Sineqela lethu le-R & D kunye nemizi-mveliso yethu, sithatha ithuba le-R&D yethu etyebileyo, imveliso eqeqeshwe kakuhle, yaphumelela igama elihle kubathengi behlabathi ngokubanzi.
