A. Incamake
Ibisobanuro bya press-ihuza umuhuza twateje imbere ni
incamake mu mbonerahamwe ya II.
Imbonerahamwe II, "Ingano" bisobanura ubugari bwumugabo (ibyo bita "Ingano ya Tab") muri mm.
B. Gukwirakwiza Imbaraga Zikwiye Kugena Urwego
Nintambwe yambere yo gukanda-guhuza igishushanyo mbonera, tugomba
menyesha urwego rukwiye rwingufu.
Kubwiyi ntego, deformasiyo iranga igishushanyo cya
guterimbere no kunyura mu bishushanyo bishushanyije, nkuko bigaragara
mu gishushanyo cya 2. Byerekanwe ko imbaraga zo guhuza ziri mumurongo uhagaze,
mugihe ingano yubunini hamwe nu mwobo wa diametre biri muri
umurongo utambitse.
C. Kugena Imbaraga Zitumanaho
Imbaraga ntarengwa zo guhuza zagenwe na (1)
gutegura umugambi wo guhangana wabonetse nyuma yo kwihangana
ibizamini muri vertical axis hamwe nintangiriro yo guhuza imbaraga muri horizontal
umurongo, nkuko bigaragara ku gishushanyo cya 3 mubishushanyo, na (2) gushakisha
imbaraga zidasanzwe zo guhuza nkukwemeza guhuza kwaba
munsi kandi ihamye.
Biragoye gupima imbaraga zo guhuza kubitangazamakuru bihuza mubikorwa, nuko twabibonye kuburyo bukurikira:
(1) Kwinjiza amaherere mu mwobo, ufite
diameter zitandukanye zirenze urugero rwateganijwe.
(2) Gupima ubugari bwa terefone nyuma yo kwinjiza kuva kuri
igice cyambukiranya icyitegererezo (urugero, reba Ishusho 10).
(3) Guhindura ubugari bwa terefone yapimwe muri (2) muri
imbaraga zo guhuza ukoresheje deformasiyo iranga
igishushanyo cya terminal cyabonetse mubyukuri nkuko bigaragara muri
Igishushanyo 2.
Imirongo ibiri ya terefone ihindagurika isobanura imwe ya
ntarengwa na minisiteri ntoya bitewe no gutatanya muri
uburyo bwo gukora.
Imbonerahamwe II Gutandukanya Umuhuza twateje imbere
Biragaragara ko imbaraga zo guhuza zabyaye hagati
guterimbere kandi nubwo-ibyobo bitangwa no guhuza bibiri
igishushanyo cya terefone no kunyura mu mwobo ku gishushanyo cya 2, iyo
bisobanura imiterere iringaniye ya compression yo gutambuka no kunyura mu mwobo.
Twagennye (1) imbaraga ntarengwa zo guhuza
asabwa gukora imikoranire irwanya itumanaho na
nubwo-ibyobo biri hasi kandi bihamye mbere / nyuma yo kwihangana
ibizamini byo guhuza ingano ntoya ya minisiteri na
ntarengwa unyuze mu mwobo, na (2) imbaraga ntarengwa
bihagije kugirango wizere ko irwanya izirinda hagati yegeranye
unyuze mu mwobo urenze agaciro kagenwe (109Q kuri ibi
iterambere) ukurikira ibizamini byo kwihangana kuri
guhuza ibipimo ntarengwa bya minisiteri na minisiteri
unyuze mu mwobo wa diametre, aho kwangirika muri insulation
kurwanywa biterwa no kwinjiza amazi muri
agace kangiritse (gusiba) muri PCB.
Mu bice bikurikira, uburyo bukoreshwa mukumenya
imbaraga ntarengwa kandi ntarengwa zo guhuza.
D. Kumenyekanisha imbaraga ntarengwa
Birashoboka ko interlaminar delamination muri PCB itera
kugabanya ubukana bwokwirinda kubushyuhe bwo hejuru no muri
ikirere cyuzuye iyo gikorewe imbaraga nyinshi zo guhura,
ikaba ikorwa no guhuza ntarengwa
ingano ya terminal na byibuze unyuze mu mwobo.
Muri iri terambere, imbaraga zemewe zo guhuza imbaraga
yabonetse ku buryo bukurikira;(1) agaciro k'igerageza ka
intera ntarengwa yemewe yo gukumira "A" muri PCB yari
yabonetse mubigeragezo mbere, (2) biremewe
uburebure bwa delamination bwabazwe geometrike nka (BC A) / 2, aho "B" na "C" aribibuga byanyuma na
unyuze mu mwobo wa diameter, (3) gusiba nyirizina
uburebure muri PCB kubintu bitandukanye byanyuze mu mwobo byabaye
yabonetse mubigeragezo kandi yapanze kuburebure bwatandukanijwe
v. Intangiriro yo guhuza imbaraga igishushanyo, nkuko bigaragara ku gishushanyo cya 4
mubishushanyo.
Hanyuma, imbaraga ntarengwa zo guhuza zagenwe bityo
nkaho kutarenza uburebure bwemewe bwo gusiba.
Uburyo bwo kugereranya imbaraga zo guhuza ni kimwe na
byavuzwe mu gice kibanziriza iki.
E. Igishushanyo mbonera
Imiterere ya terminal yarakozwe kugirango itange umusaruro
imbaraga zo guhuza (N1 kugeza N2) muburyo bwateganijwe binyuze mu mwobo
urwego rwa diameter ukoresheje ibintu bitatu byanyuma
buryo (FEM), harimo n'ingaruka zo guhindura ibintu mbere ya plastike
gushishikarira gukora.
Kubwibyo, twafashe itumanaho, rimeze nka an
"N-shusho yambukiranya igice" hagati yumwanya uhuza hafi ya
hepfo, byabyaye imbaraga zo guhuza hafi
murwego rwateganijwe binyuze mu mwobo wa diameter, hamwe na
umwobo-umwobo hafi yisonga ryemerera kwangirika kwa PCB kuba
yagabanutse (Ishusho 5).
Yerekanwa ku gishushanyo cya 6 ni urugero rwibice bitatu
Icyitegererezo cya FEM nimbaraga zo kubyitwaramo (ni ukuvuga imbaraga zo guhuza) na
igishushanyo cyo kwimurwa cyabonetse kubisesenguye.
F. Gutezimbere Amabati akomeye
Hariho uburyo butandukanye bwo kuvura kuburizamo
okiside ya Cu kuri PCB, nkuko byasobanuwe muri II - B.
Kubijyanye no gutunganya ibyuma byo hejuru, nka
amabati cyangwa ifeza, guhuza amashanyarazi kwizerwa-gukanda
tekinoroji irashobora gukemurwa no guhuza hamwe
bisanzwe Ni isahani.Icyakora kubijyanye na OSP,amabati kuri terefone agomba gukoreshwa kugirango yizere igihe kirekireijambo guhuza amashanyarazi kwizerwa.
Ariko, amabati asanzwe ashyira kumurongo (kuri
urugero, ya 1ltm yubugari) ibyara gusibaamabatimugihe cyo kwinjiza itumanaho.(Ifoto. "A" mu gishushanyo 7)
kandi uku gusiba-birashoboka ko bitera imirongo migufi hamweihererekanyamakuru.
Kubwibyo twateje imbere ubwoko bushya bwamabati
isahani, itayobora amabati yose yakuweho kandiitanga igihe kirekire cyumuriro wamashanyarazi kwizerwaicyarimwe.
Ubu buryo bushya bwo kubumba bugizwe na (1) amabati yoroheje
isahani kuri underplating, (2) uburyo bwo gushyushya (amabati-yerekana),
ikora ibyuma bikomeye bya alloy layer hagati ya
gushira hamwe n'amabati.
Kuberako ibisigisigi byanyuma byamabati, niyo mpamvu
yo gusiba-kuri, kuri terminal iba inanutse cyane kandi
Ikwirakwiza idahuye kumurongo wa alloy, nta gusibaByaamabati yagenzuwe mugihe cyo kwinjiza (Ifoto "b" muriIgishushanyo 7).
