Ekyuma Ekikuba ebitabo ekya ASM DEK 265

DEK printer kye ki 265

DEK printer 265 ye printa ya solder paste ekola bulungi mu bujjuvu eya otomatiki eyatongozebwa kkampuni ya DEK (kati ASM Assembly Systems). Ekozesebwa nnyo mu layini z’okufulumya SMT (surface mount technology) era nga ekoleddwa okukuba PCB (printed circuit board) solder paste mu ngeri entuufu. Esaanira ebyuma ebikozesebwa abantu, ebyuma ebikozesebwa mu mmotoka, ebyuma by’empuliziganya n’emirimu emirala.

Ebirungi ebikulu

Okukuba ebitabo mu ngeri entuufu ennyo

Nga twettanira enkola ey’omulembe ey’okulaga ebifaananyi (nga 2D/3D SPI detection), esobola okutuuka ku ±15μm okukuba ebitabo obutuufu, okutuukiriza ebyetaago by’ebitundu ebirungi nga 01005 ne 0.3mm pitch BGA.

Okukola obulungi ennyo

Okukuba ebitabo ku sipiidi ya waggulu (okutuuka ku 300mm/s) n’okukyusa layini amangu (okuwagira okukyusa pulogulaamu mu ngeri ey’otoma) okulongoosa UPH (unit hourly production capacity) ya layini y’okufulumya.

Okutebenkera okw’amaanyi

Enkola y’okufuga enzigi (closed-loop control system) ne tekinologiya ow’okutereeza puleesa mu kiseera ekituufu okukakasa nti okukuba ebitabo kukwatagana.

Okukyukakyuka okw’amaanyi

Awagira ebyetaago by’enkola eby’enjawulo (solder paste, glue, red glue, n’ebirala) ne sayizi za PCB ez’enjawulo (okutuuka ku 510×460mm).

Kyangu okukozesa

Humanized HMI interface (nga Windows-based operating software), ewagira okulondoola okuva ewala n’okwekenneenya data.

ASM DEK Okukuba ebitabo Omusingi gw’okukola

Okuteeka wansi w’ebintu (substrate positioning).

PCB eyingira mu kifo ky’okukuba ebitabo ng’eyita mu luguudo lw’okutambuza, etereezebwa enkola y’okusiba, era enkola y’okulaba (CCD camera) eraga okukwatagana kw’ensonga y’akabonero.

Okusiba akatimba k’ekyuma

Ekyuma ekiyitibwa steel mesh ne PCB biyungibwa nga biyita mu vacuum adsorption oba mechanical clamping okukakasa nti tewali bbanga.

Okukuba ebitabo mu solder paste

Ekisekula (ekyuma oba ekintu kya polyurethane) kinyigiriza ekikuta kya solder ku puleesa n’enkoona ebiteekeddwawo, ne kigikuba okuyita mu kifo ekiggulwawo eky’akatimba k’ekyuma okutuuka ku paadi ya PCB.

Okuggya ebikuta n’okuzuula

Ekyuma kino kyawuddwa ku PCB (sipiidi ya demolding etereezebwa), era ebika ebimu bibaamu omulimu gw’okuzuula solder paste ogwa 3D.

DEK Ekyuma Ekikuba Ebisumuluzo Ebikwata ku

Ebipimo by’Ekintu

Sayizi ya PCB esinga obunene 510×460mm

Obutuufu bw’okukuba ebitabo ±15μm (Cpk≥1.0)

Sipiidi y’okukuba ebitabo 50-300mm/s (etereezebwa)

Puleesa y’okusenya 5-20kg (esobola okuteekebwateekebwa)

Stencil obuwanvu obuwagira 0.1-0.3mm

Ebyetaago by’amasannyalaze 220VAC/50-60Hz, 1.5kW

Puleesa y’ensibuko y’empewo 0.5-0.7MPa

Ebikulu ebirimu

Enkola ya scraper ey’amagezi

Puleesa, sipiidi, n’enkoona bisobola okufugibwa mu ngeri ya pulogulaamu okusobola okutuukagana n’engeri ez’enjawulo ez’ekikuta kya solder.

Omulimu gw’okuyonja ogw’omulembe

Okwoza akatimba k’ekyuma mu ngeri ez’enjawulo nga dry wipe, wet wipe, vacuum adsorption, n’ebirala okukendeeza ku bisigalira.

Dizayini ya modulo

Kyangu okulabirira n’okulongoosa (nga scraper module ne camera module bisobola okukyusibwa amangu).

Okulondoola data

Okuwagira enkola ya MES docking okuwandiika parameters z'okukuba ebitabo ne data ey'omutindo.

DEK Printing Machine Ensobi eza bulijjo n’ebirowoozo by’okuddaabiriza

1. Okukyama okukuba ebitabo

Ensonga eziyinza okubaawo:

Mark point recognition error (obucaafu oba ekitangaala ekitamala).

Stencil oba PCB positioning si nnywevu.

Emitendera gy’okugonjoola ensonga eno:

Yoza ekifo we bassaako akabonero era otereeze ensibuko y’ekitangaala kya kkamera.

Kebera oba puleesa y’empewo y’enkola y’okusiba (clamping mechanism) ya bulijjo.

2. Solder paste pull tip/solder etamala

Ensonga eziyinza okubaawo:

Sipiidi y’okuggyamu ekyuma (demolding speed) ya mangu nnyo oba okusika omuguwa kw’akatimba k’ekyuma tekumala.

Puleesa ya scraper tekwatagana oba ebbugumu lya solder paste terimala.

Emitendera gy’okugonjoola ensonga eno:

Kendeeza ku sipiidi y’okuggyamu ekikuta (ekisemba 0.1-0.5mm/s).

Kalibrate level ya scraper era okebere viscosity ya solder paste.

3. Okuzibikira kwa stencil

Ensonga eziyinza okubaawo:

Solder paste nkalu oba emirundi gy’okwoza tegimala.

Emitendera gy’okugonjoola ensonga eno:

Yongera ku frequency y’okusiimuula ennyo (omulundi gumu buli 5-10 prints).

Kikyuseemu solder paste n’amazzi amalungi.

4. Alaamu y’ekyuma (puleesa y’empewo/okulemererwa kwa servo) .

Ebiyinza okuvaako ensonga eno:

Okukulukuta kw’empewo oba servo drive okubuguma ennyo.

Emitendera gy’okugonjoola ensonga eno:

Kebera oba puleesa y’ensibuko y’empewo enywevu.

Okwoza ekyuma ekinyogoza mmotoka ya servo.

ASM DEK Printing Machine Ebiteeso ku ndabirira

Okuddaabiriza buli lunaku

Okwoza ekikuta kya solder ekisigadde ku luguudo, akatimba k’ekyuma ne scraper.

Kebera ekipima puleesa y’empewo ne ffilta.

Okuddaabiriza buli luvannyuma lwa kiseera

Siiga linear guide ne lead screw buli mwezi.

Kalibrate enkola y’okulaba ne sensa ya puleesa y’okusenya.

DEK 265 efuuse ebyuma ebikulu mu layini y’okufulumya SMT olw’obutuufu bwayo obw’amaanyi, obutebenkevu obw’amaanyi n’emirimu egy’amagezi. Okuyita mu nkola ey’omutindo n’okuddaabiriza okuziyiza, omuwendo gw’okulemererwa guyinza okukendeezebwa ennyo era n’amakungula g’okukuba ebitabo gasobola okulongoosebwa. Ku kulemererwa okuzibu, kirungi okututuukirira okuddaabiriza ng’okozesa sipeeya ow’olubereberye.

Singa ebipimo ebisingawo ebikwata ku nsonga oba eby’okugonjoola ebizibu ebitongole byetaagibwa, embeera ez’enjawulo ez’okukozesa zisobola okuweebwa okwongera okwekenneenya.
