Hod yokhala ndi bowo kudzera pa bowo limadziwikanso kuti muli bowo. Pofuna kukwaniritsa zofunika za makasitomala, bolodi ya madera iyenera kulumikizidwa. Pambuyo pa zochitika zambiri, njira zolumikizira zachikhalidwe za kuvomerezedwa zimasinthidwa, ndipo mabwalo ozungulira obisalira ndi odulira amamalizidwa ndi ma mesh oyera. dzenje. Kupanga zokhazikika komanso zabwino.

Via bood amatenga gawo la zigawo ndi mizere. Kukula kwa mafakitale amagetsi kumalimbikitsanso kukula kwa pcb, komanso kumayikanso zofunikira kwambiri pa bolodi yopanga ndikuwongolera mawonekedwe. Via Hole Opting Technology idayamba, ndipo ikuyenera kukwaniritsa zofunikira zotsatirazi:

Ndi chitukuko cha zinthu zamagetsi kulowera "kuwala, wochepa thupi, lalifupi komanso laling'ono", ma pcb apanganso mphamvu zambiri komanso zovuta kwambiri. Chifukwa chake, ambiri a SMT ndi BGA PCBS adawonekera, ndipo makasitomala amafunikira kulowerera pamene zigawo zikuluzikulu, makamaka ntchito zisanu:

. Makamaka tikamayika dzenje pa BGA Pad, tiyenera kupanga kaye

(2) Pewani zotsalira za flux mu vias;

Pamalo a Phiri lokwera, makamaka kukweza kwa BGA ndi IC, Pulani ya Puled Kuwongoletsera kudzera pa mpira wa tini, kuti mufikire makasitomala njira yolembera mabowo kudzera m'mabowo omwe amatha kufotokozedwa kuti ndi osiyana. Njira yoyenda ili makamaka ndipo njira yolamulira ndizovuta. Nthawi zambiri pamakhala zovuta monga dontho lamafuta nthawi yotentha ya mpweya ndi msirikali wogulitsira mankhwala; Kuphulika kwa mafuta mutachiritsa. Tsopano molingana ndi zochitika zenizeni, mitundu yolumikizira ya PCB imafotokozedwa mwachidule, ndipo kufananizirana ndi mafotokozedwe ena kumachitika ndi zovuta komanso zovuta:
Chidziwitso: Malangizo ogwirira ntchito mpweya wotentha ndikugwiritsa ntchito mpweya wotentha kuti muchotse msirikali wowonjezera pamtunda, ndipo msirikali wotsalira amapezeka pamizere, yomwe ndi njira yothandizira kwambiri.

I. Bowgg yotsekera pambuyo pa mizere yotentha

Njira yoyenda ndi: Good Log Logr Shosse → hal → Pulani Hod Bod → Kuchiritsa. Njira yosasunthika imakhazikitsidwa chifukwa chopanga. Pambuyo pa mpweya wotentha watulutsidwa, chinsalu cha aluminiyamu kapena chophimba cha inki chimagwiritsidwa ntchito kuti mutsirize zowombera zomwe zimafunikira ndi makasitomala azipatala zonse. Inking inki imatha kukhala inki yojambulidwa kapena thermosetting ink. M'malo owonetsetsa mtundu womwewo wa filimu yonyowa, ndibwino kugwiritsa ntchito inki yomweyo monga bolodi. Izi zitha kuonetsetsa kuti mabowo sangataye mafuta pambuyo pa mpweya wotentha, koma ndizosavuta kuyambitsa inki yolumikizira kuti idetse board komanso osagwirizana. Makasitomala amakonda kugwira ntchito zonama (makamaka ku BGA) pakukwera. Makasitomala ambiri savomereza njirayi.

Ii. Kutentha kwapamwamba kwa mpweya kutsogolo

1. Gwiritsani ntchito pepala la aluminim kuti mugule dzenje, khazikitsani, ndikupukutira bolodi kuti musinthe
Njira yaukadaulo iyi imagwiritsa ntchito makina okwera a CNC kuti abowole pepala lomwe likufunika kulumikizidwa kuti apange chophimba, ndikupukutira dzenje kuti dzenje likhale lodzaza. Inki ya Hop Call itha kugwiritsidwanso ntchito ndi inki ya thermosetting, ndipo mawonekedwe ake ayenera kukhala olimba. , Shrin shrin ndi yaying'ono, ndipo gulu lolumikizirana ndi khoma la dzenje ndilabwino. Njira yoyenda ndi: Pulogalamu Yothandizira → Pulani Holl → Makonzedwe → Mapata Plate → Kutayika Njira iyi imatha kuwonetsetsa kuti dzenje la Pule ili ndi lathyathyathya, ndipo sipadzakhala zovuta zina monga kuphulika kwa mafuta ndi dontho lamafuta m'mphepete mwa dzenjelo mumitseko yotentha. Komabe, njirayi imafunikira kukula kwa mkuwa kuti apange makulidwe amkuwa a khoma la bowo. Chifukwa chake, zofuna za kudula mitengo yonse ndizokwera kwambiri, ndipo magwiridwe antchito opera amakhalanso pamwamba kwambiri, kuti awonetsetse kuti remen pamkuwa imachotsedwa kwathunthu, ndipo mkuwa pamwamba ndi wosayera ndipo wosadetsedwa. Mafakitale ambiri a PCB alibe nthawi ya mkuwa, ndipo magwiridwe antchito sakwaniritsa zofunikirazo, zomwe sizigwiritsidwa ntchito kwambiri ndi njirayi mu mafakitale a PCB.

2. Gwiritsani ntchito pepala la aluminim kuti mugule dzenje ndikusindikiza chikwangwani
Njirayi imagwiritsa ntchito makina okwera a CNC kuti abowole pepala lomwe likufunika kulumikizidwa kuti apange chinsalu, gwiritsani ntchito pazenera lopitilira mphindi 30 Njira yoyenda ndi iyi: Pulani-Screed-Screen-Screen-Screet-Kuvekedwa - kuchiritsa
Izi zitha kuwonetsetsa kuti dzenje lomwe lili ndi mafuta limakutidwa ndi mafuta, bowo la Pulging ndi lathyathyathya, ndipo mtundu wa filimu yonyowa ndizofanana. Pambuyo pa mpweya wotentha watulutsidwa, zitha kuwonetsetsa kuti dzenje la kudzera mwa kudzera pabowo silinandibise mikanda, koma ndizosavuta kuyambitsa inki m'dzenje pambuyo pochiritsa mapiritsi osachiritsa; Mphepo yotentha itatsitsidwa, m'mphepete mwa mawu ophulika ndi mafuta zimachotsedwa. Ndikosavuta kuwongolera kapangidwe ka njirayi. Akatswiri opanga njira ayenera kugwiritsa ntchito njira zapadera komanso magawo kuti awonetsetse kuti mabowo a pulawo.

3. Masamba a aluminium adalumikizidwa m'dzenjemo, yopangidwa, yochiritsidwa kale, ndikupukutidwa pamaso pa msipu wa asitikali.
Gwiritsani ntchito makina obalira a CNC kuti abowole pepala la aluminimu lomwe limafuna kudula mabowo kuti apange chophimba, ikani pa makina osindikizira osindikizira. Mabowo ofuula ayenera kukhala odzaza ndi mbali zonse ziwiri. Atachiritsa, bolodi ndi nthaka yothandizira pansi. Kutuluka kwa ntchito ndi: Pre-Pre-Search-Sear-Carding-Bulder-board-board-board akukana. Chifukwa njirayi imagwiritsa ntchito cald povala kuti muwonetsetse kuti dzenje litatsika kapena liphulika, koma zikavuta kuthetsa vuto la mikanda ndi tini pa via maenje, kotero makasitomala ambiri sawalandira.

4.
Njirayi imagwiritsa ntchito screen ya 36T (43T), yokhazikitsidwa pamakina osindikizira, pogwiritsa ntchito mbale yopumira, ndikumaliza mabowo onse, njira yodziyimira-silika-kuwonekera. Nthawi ya ntchito ndiyochepa, ndipo kuchuluka kwa zida ndi zapamwamba. Zitha kuwonetsetsa kuti mabowo sangataye mafuta ndipo kudzera m'mabowo sadzatsekedwa pambuyo pa mpweya wotentha, koma chifukwa chophimba silika chimagwiritsidwa ntchito podula, pali mpweya wambiri mu Vais. Pa nthawi yochiritsa, mpweya umakula ndikusweka kudutsa chigoba, ndikupangitsa mivi ndi kusagwirizana. Padzakhala malata ochepa kudzera mabowo a mizere yotentha. Pakadali pano, atatha kuyesa kwakukulu, kampani yathu yasankha mitundu yosiyanasiyana ya ma Inks, kusintha kupsinjika kwa kusindikiza kwa zenera, etc., ndikuthetsa nthitiyo, ndipo yatengera njirayi yopanga misa.
