Kodi Tiyenera Kuganizira Chiyani Posankha Solder, PCB ndi Packaging Equipment?

Mu PCBA msonkhano, kusankha zinthu n'kofunika kwambiri kuti bolodi ntchito ndi kudalirika.Nazi malingaliro ena a solder, PCB ndi kusankha kwazinthu zonyamula:

Malingaliro osankha solder

1. Lead Free Solder vs Lead Solder

Solder wopanda lead ndi wamtengo wapatali chifukwa cha chilengedwe chake, koma ndikofunikira kuzindikira kuti ali ndi kutentha kwambiri.Wotsogolera solder amagwira ntchito pa kutentha kochepa, koma pali zoopsa zachilengedwe ndi thanzi.2.

2. Malo osungunuka

Onetsetsani kuti malo osungunuka a solder osankhidwa ndi oyenerera kutentha kwa ndondomeko ya msonkhano ndipo sichidzawononga zowonongeka kwa zigawo zowonongeka.

3. Madzi

Onetsetsani kuti solder ili ndi madzi abwino kuti muwonetsetse kuti kunyowetsa kokwanira ndi kugwirizana kwa ziwalo za solder.

4. Kukana kutentha

Pazogwiritsa ntchito kutentha kwambiri, sankhani solder yokhala ndi kutentha kwabwino kuti mutsimikizire kukhazikika kwa mgwirizano wa solder.

Zolinga zosankhidwa za PCB

1. Zinthu zapansi

Sankhani gawo loyenera la gawo lapansi, monga FR-4 (magalasi fiber reinforced epoxy resin) kapena zida zina zothamanga kwambiri, kutengera zomwe mukufuna kugwiritsa ntchito komanso pafupipafupi.

2. Chiwerengero cha zigawo

Dziwani kuchuluka kwa zigawo zofunika kuti PCB ikwaniritse zofunikira zamayendedwe amawu, ndege zapansi ndi mphamvu.

3. Khalidwe impedance

Mvetsetsani kusakhazikika kwazinthu zosankhidwa za gawo lapansi kuti muwonetsetse kukhulupirika kwa ma siginecha ndikufananiza zofunika zamitundu iwiri.

4. Thermal Conductivity

Pazogwiritsa ntchito zomwe zimafuna kutenthedwa, sankhani gawo lapansi lokhala ndi matenthedwe abwino kuti muchepetse kutentha.

Zoganizira pakusankha zinthu za phukusi

1. Mtundu wa phukusi

Sankhani mtundu woyenera wa phukusi, monga SMD, BGA, QFN, ndi zina zotero, kutengera mtundu wagawo ndi zofunikira pakugwiritsa ntchito.

2. Zinthu za encapsulation

Onetsetsani kuti zinthu zosankhidwa za encapsulation zikukwaniritsa zofunikira zamagetsi ndi zamakina.Ganizirani zinthu monga kutentha, kukana kutentha, mphamvu zamakina, etc.

3. Phukusi ntchito matenthedwe

Pazigawo zomwe zimafuna kutentha, sankhani phukusi lokhala ndi kutentha kwabwino, kapena ganizirani kuwonjezera choyatsira kutentha.

4. Kukula kwa phukusi ndi matayala a pini

Onetsetsani kuti kukula ndi mapini a phukusi losankhidwa ndi loyenera masanjidwe a PCB ndi makonzedwe a zigawo.

5. Kuteteza chilengedwe ndi kukhazikika

Ganizirani kusankha zinthu zokondera zachilengedwe zomwe zimagwirizana ndi malamulo ndi miyezo yoyenera.

Posankha zipangizozi, nkofunika kugwira ntchito limodzi ndi opanga PCBA ndi ogulitsa kuonetsetsa kuti kusankha zinthu kumakwaniritsa zofunikira za ntchito yeniyeni.Komanso, kumvetsetsa ubwino, kuipa ndi makhalidwe a zipangizo zosiyanasiyana, komanso kuyenera kwawo ntchito zosiyanasiyana, n’kofunika kwambiri popanga chisankho mwanzeru.Kutengera chikhalidwe chowonjezera cha solder, PCB ndi zida zonyamula zimatsimikizira magwiridwe antchito ndi kudalirika kwa PCBA.

Zhejiang NeoDen Technology Co., LTD., yomwe idakhazikitsidwa mu 2010, ndi katswiri wopanga makina opangira ma SMT ndi malo, uvuni wa reflow, makina osindikizira a stencil, chingwe chopangira SMT ndi Zida zina za SMT.Tili ndi gulu lathu la R & D ndi fakitale yathu, kugwiritsa ntchito mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, adapambana mbiri yabwino kuchokera kwamakasitomala padziko lonse lapansi.

M'zaka khumizi, tidapanga NeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 ndi zinthu zina za SMT, zomwe zidagulitsidwa padziko lonse lapansi.Pakadali pano, tagulitsa makina opitilira 10,000pcs ndikutumiza kumayiko opitilira 130 padziko lonse lapansi, ndikukhazikitsa mbiri yabwino pamsika.Mu Ecosystem yathu yapadziko lonse lapansi, timagwirizana ndi bwenzi lathu lapamtima kuti tipereke ntchito yotseka kwambiri yotsatsa, ukadaulo wapamwamba komanso chithandizo chaukadaulo chaluso.
