Daim Ntawv Ceeb Toom (Kev Siv Hlau Thiab Kev Teeb Tsa)

1. Kev teeb tsa

Thaum koj muab ib yam khoom siv uas muaj tus pin terminal ntsia rau ntawm lub rooj tsavxwm luam tawm, thov muab tus pin terminal ntxig rau ntawm qhov ntawm lub rooj tsavxwm. Yog tias cov khoom raug nias kom lub terminal tsis nyob hauv qhov, tus pin terminal yuav raug thawb mus rau sab hauv ntawm cov khoom thiab lub suab yuav tsis ruaj khov.

2. Ob sab ntawm lub rooj tsavxwm

Thov tsis txhob siv lub rooj tsavxwm uas muaj ob sab. Yog tias cov hlau nplaum uas yaj lawm kov lub hauv paus ntawm lub qhov kawg ntawm tus pin, ib feem ntawm lub thawv yas yuav yaj thiab lub suab yuav tsis ruaj khov.

3. Cov xwm txheej ntawm kev vuam

(1) Cov xwm txheej ntawm kev sib txuas ntawm cov kav hlau txais xov rau hom davhlau ya nyob twg

• Kub: tsis pub dhau 260 ° C ± 5 ° C
• Lub Sijhawm: tsis pub dhau 10 ± 1 vib nas this.
• Qhov chaw vuam yog cov hlau lead tsis suav nrog 1.5 hli ntawm lub cev khoom.

(2) Thov tsis txhob khaws cov khoom ncaj qha rau hauv pem teb yam tsis muaj dab tsi nyob hauv qab kom tsis txhob muaj qhov chaw ntub thiab/lossis qhov chaw muaj plua plav.

(3) Thov tsis txhob khaws cov khoom rau hauv qhov chaw xws li qhov chaw ntub dej lossis qhov chaw uas raug tshav ntuj ncaj qha lossis kev co ntau dhau.

(4) Thov siv cov khoom tam sim ntawd tom qab qhib lub pob, vim tias cov yam ntxwv yuav txo qis qhov zoo, thiab / lossis yuav puas tsuaj vim yog khaws cia rau hauv qhov xwm txheej tsis zoo.

(5) Thov nco ntsoov sab laj nrog peb tus neeg sawv cev muag khoom lossis tus kws ua haujlwm thaum twg cov khoom yuav tsum tau siv rau hauv cov xwm txheej uas tsis tau teev saum toj no.

4. Ib puag ncig ua haujlwm

Cov khoom no yog tsim los rau kev siv rau hauv ib puag ncig ib txwm muaj (qhov kub thiab txias ib txwm muaj, av noo thiab qhov siab ntawm huab cua).

Tsis txhob siv cov khoom no rau hauv huab cua uas muaj tshuaj lom neeg xws li roj chlorine, kua qaub lossis roj sulfide.

Cov yam ntxwv yuav lwj los ntawm kev tshuaj lom neeg nrog cov khoom siv hauv cov khoom.

(2) Cov xwm txheej soldering los ntawm soldering hlau rau tus pin davhlau ya nyob twg hom

• Kub: tsis pub dhau 350 ± 5 ° C
• Lub Sijhawm: tsis pub dhau 3.0 ± 0.5 vib nas this.
• Qhov chaw vuam yog cov hlau lead tsis suav nrog 1.5 hli ntawm lub cev khoom

(3) Reflow soldering mob rau qhov chaw mounting hom

• Cov ntaub ntawv kub: Daim duab 1
• Tus naj npawb ntawm cov sijhawm: Tsis pub dhau 2 qhov siab tshaj plaws

4. Ntxuav

Thov tsis txhob ntxuav, vim tias cov khoom no tsis yog ib qho qauv kaw.

5. Tom qab muab cov khoom tso rau hauv lub thawv

(1) Yog tias cov khoom ntab los ntawm lub rooj tsavxwm luam tawm, thov tsis txhob thawb nws. Thaum nias, lub davhlau ya nyob twg pin raug thawb rau hauv cov khoom thiab lub suab yuav tsis ruaj khov.

(2) Thov tsis txhob siv zog (kev co) rau cov khoom. Yog tias siv zog, lub thawv yuav tawg.

(3) Yog tias lub thawv tawg lawm, thov tsis txhob rov sib sau ua ke. Txawm tias nws zoo li rov qab mus rau qhov qub, lub suab yuav tsis ruaj khov.

(4) Thov tsis txhob tshuab cua ncaj qha rau ntawm cov khoom. Cov cua uas tshuab siv zog rau lub diaphragm piezoelectric los ntawm lub qhov tso suab; tej zaum yuav muaj kab nrib pleb thiab tom qab ntawd cov suab yuav tsis ruaj khov. Tsis tas li ntawd xwb, muaj qhov ua tau tias lub thawv yuav tawg.

Daim Ntawv Ceeb Toom (Kev Tswj)

1. Cov khoom no siv cov khoom siv piezoelectric ceramic. Thov ceev faj thaum tuav, vim tias cov ceramic yuav tawg thaum siv zog ntau dhau.
2. Thov tsis txhob siv zog rau lub diaphragm piezoelectric los ntawm lub qhov tso suab. Yog tias siv zog, yuav muaj kab nrib pleb thiab lub suab yuav tsis ruaj khov.
3. Thov tsis txhob muab cov khoom poob lossis siv kev co lossis kev hloov pauv kub rau nws. Yog tias yog li ntawd, LSI yuav raug rhuav tshem los ntawm lub zog them (surge voltage) tsim tawm.

qhia ib qho piv txwv ntawm kev tsav tsheb siv zener diode.

Daim Ntawv Ceeb Toom (Tsav Tsheb)

1. Kev hloov pauv Ag yuav tshwm sim yog tias DC voltage siv rau cov khoom hauv qab qhov chaw noo noo siab. Thov tsis txhob siv nws hauv qab qhov chaw noo noo siab thiab tsim lub voj voog kom tsis txhob siv DC voltage.
2. Thaum tsav cov khoom los ntawm IC, thov ntxig qhov tsis kam ntawm 1 txog 2kΩ hauv series. Lub hom phiaj yog los tiv thaiv IC thiab kom tau txais lub suab ruaj khov. (Thov saib daim duab 2a). Ntxig lub diode ua ke rau cov khoom muaj tib qho txiaj ntsig. (Thov saib daim duab 3b)
3. Cov tshuaj Flux lossis Coating Agent, thiab lwm yam, Ntau Yam Tshuaj Solvents Nws muaj peev xwm rau cov kua tshuaj solvent nkag mus rau hauv cov khoom, vim tias cov khoom no tsis yog ib qho qauv kaw. Yog tias cov kua nkag mus rau hauv thiab txuas rau lub diaphragm piezoelectric, nws qhov kev co yuav raug txwv. Yog tias txuas rau qhov sib txuas hluav taws xob, qhov kev sib txuas hluav taws xob yuav tsis ua haujlwm.

Yuav kom tiv thaiv tau qhov suab tsis ruaj khov, thov tsis txhob cia kua nkag mus rau hauv cov khoom.
