Tugomba gukora iki mbere ya SMT PCBs mugihe cyo guterana kwa PCB?

PCBFuture ifite uruganda rukora smt, rushobora gutanga serivise zo guteranya SMT kubikoresho bito 0201.Ninkunga yuburyo butandukanye bwo gutunganya nkainteko ya PCBserivisi za pcba OEM.Noneho, nzakumenyesha Ni ubuhe bugenzuzi bugomba gukora mbere yo gutunganya SMT PCB?

 1.Igenzura ryibigize SMT

Ibintu byubugenzuzi birimo: solderability, pin coplanarity hamwe nibikoreshwa, bigomba gukopororwa nishami rishinzwe ubugenzuzi.Kugirango tugerageze kugabanura ibice, turashobora gukoresha ibyuma bitagira umuyonga kugirango dushyireho ibice hanyuma twibire mu nkono y'amabati kuri 235 ± 5 ℃ cyangwa 230 ± 5 and, hanyuma tuyikure kuri 2 ± 0.2s cyangwa 3 ± 0.5s.Tugomba gusuzuma imiterere yo gusudira munsi ya microscope ya 20x.Birasabwa ko ibice birenga 90% byo gusudira kumpera yibigize bitose hamwe namabati.

Amahugurwa yacu ya SMT azakora munsi yubugenzuzi bugaragara:

1.1 Turashobora kugenzura impera zo gusudira cyangwa pin hejuru yibice bigize okiside cyangwa kwanduza muburyo cyangwa ikirahure kinini.

1.2 Agaciro kizina, ibisobanuro, icyitegererezo, ubunyangamugayo, nubunini bwo hanze bwibigize bigomba kuba bihuye nibisabwa PCB.

1.3 Amapine ya SOT na SOIC ntashobora guhinduka.Kubikoresho byinshi-biyobora QFP ifite icyerekezo cyambere kiri munsi ya 0,65mm, coplanarity ya pin igomba kuba munsi ya 0.1mm kandi dushobora kugenzura nubushakashatsi bwa optique.

1.4 Kuri PCBA isaba isuku yo gutunganya patch ya SMT, ikimenyetso cyibigize ntigomba kugwa nyuma yo gukora isuku, kandi ntigishobora guhindura imikorere nubwizerwe bwibigize.Ko dushobora kugenzura amashusho nyuma yo gukora isuku.

2Igenzura rya PCB

2.1 Imiterere yubutaka bwa PCB nubunini, masike yo kugurisha, ecran ya silike, kandi binyuze mumwobo bigomba kuba byujuje ibyangombwa bisabwa kubibaho bya SMT byacapwe.Turashobora kugenzura umwanya wa padi birumvikana, ecran yacapishijwe kuri padi, kandi kunyuramo bikozwe kuri padi, nibindi.

2.2 Ibipimo bya PCB bigomba kuba bihamye, kandi ibipimo, imyobo ihagaze, hamwe nibimenyetso bya PCB bigomba kuba byujuje ibisabwa nibikoresho byumurongo.

2.3 PCB yemewe kugunama:

2.3.1 Hejuru / convex: ntarengwa 0.2mm / 50mm z'uburebure na 0.5mm ntarengwa / uburebure bwa PCB yose.

2.3.2 Hasi / hacuramye: uburebure bwa 0.2mm / 50mm n'uburebure bwa 1.5mm / uburebure bwa PCB yose.

2.3.3 Tugomba gusuzuma niba PCB yanduye cyangwa itose.

3Icyitonderwa kubikorwa bya SMT PCB:

3.1 Umutekinisiye yambara impeta ya electrostatike yagenzuwe.Mbere yo gucomeka, tugomba kugenzura ibice bya elegitoronike ya buri cyegeranyo nta makosa / kuvanga, kwangiza, guhindura, gushushanya, n'ibindi.

3.2 Gucomeka kumurongo wa PCB bigomba gutegura ibikoresho bya elegitoroniki hakiri kare, kandi ukareba icyerekezo cya capacitor polarite igomba kuba ikwiye.

3.3 Nyuma yo gucapa SMT ibikorwa birangiye, reba ibicuruzwa bifite inenge nko kutabura kwinjiza, kwinjiza inyuma, no kudahuza, nibindi, hanyuma ushire amabati yarangije PCB muburyo bukurikira.

3.4 Nyamuneka nyamuneka wambare impeta ya electrostatike mbere ya SMT PCB mugihe cyo guterana kwa PCB.Urupapuro rw'icyuma rugomba kuba hafi y'uruhu rw'intoki kandi rugashyirwa neza.Kora ukundi ukoresheje amaboko yombi.

3.5 Ibice byicyuma nka USB, NIBA sock, gukingira ikingira, tuner hamwe numuyoboro wicyambu bigomba kwambara urutoki mugihe ucomeka.

3.6 Umwanya nicyerekezo cyibigize bigomba kuba bikwiye.Ibigize bigomba kuba biringaniye hejuru yubuyobozi, kandi ibice byashyizwe hejuru bigomba kwinjizwa ku kirenge cya K.

3.7 Niba ibikoresho bidahuye nibisobanuro kuri SOP na BOM, bigomba kumenyeshwa moniteur cyangwa umuyobozi witsinda mugihe.

3.8 Ibikoresho bigomba gukoreshwa neza.Ntukomeze gukoresha PCB hamwe nibintu byangiritse, kandi oscillator ya kristu ntishobora gukoreshwa nyuma yo kumanuka.

3.9 Nyamuneka sukura kandi ugumane isuku yakazi mbere yo gukora hanyuma uve kukazi.

3.10 Wubahirize byimazeyo amategeko yimikorere yakarere.PCB mu gice cya mbere cyubugenzuzi, ahantu hagomba kugenzurwa, ahantu hafite inenge, ahantu ho kubungabunga, hamwe n’ibikoresho bike ntibyemewe ahantu hateganijwe.

4Kuki uhitamo PCBFuture kuri serivisi zo guteranya pcb?

4.1Ingwate y'imbaraga

4.1.1 Amahugurwa: Yatumije ibikoresho, bishobora gutanga amanota miliyoni 4 kumunsi.Buri nzira ifite QC ishobora kugumana ubuziranenge bwa PCB.

4.1.2 DIP umurongo utanga umusaruro: Hariho imashini ebyiri zo kugurisha imiraba, kandi dufite abakozi barenga icumi bafite uburambe bafite uburambe bwimyaka irenga itatu.Abakozi bafite ubuhanga buhanitse kandi barashobora gusudira ibikoresho bitandukanye byo gucomeka.

4.2Ubwishingizi bufite ireme, buhenze cyane

4.2.1 Ibikoresho byo murwego rwohejuru birashobora gushira ibice byuzuye neza, BGA, QFN, 0201 ibikoresho.Irashobora kandi gukoreshwa kuburugero rwicyitegererezo no gushyira ibikoresho byinshi mukiganza.

4.2.2 Byombiserivisi yo guteranya pcb, ingano ya pcbserivisi zirashobora gutangwa.

4.3Uburambe bukomeye muri SMT PCB no kugurisha PCB, kandi ni igihe cyo gutanga gihamye.

4.3.1.Inteko ya PCB na PCB yoherezwa mu Burayi no muri Amerika, kandi ireme ryemezwa n’abakiriya.

4.3.2 Gutanga ku gihe.Iminsi 3-5 isanzwe niba ibikoresho byuzuye kandi bigakemura EQ, kandi uduce duto dushobora no koherezwa kumunsi.

4.4Ubushobozi bukomeye bwo kubungabunga kandi bwiza muri serivisi nyuma yo kugurisha

4.4.1 Injeniyeri yo kubungabunga afite uburambe bukomeye kandi barashobora gusana PCB zifite inenge zatewe no gusudira ibintu bitandukanye.Turashobora kwemeza igipimo cyo guhuza buri PCB.

4.4.2 Serivise yabakiriya izitabira amasaha 24 kandi ikemure ibibazo byawe byihuse.
