Thermal shock test inowanzonzi tembiricha yekuvhunduka kuyedzwa kana tembiricha bhasikoro, yakakwirira uye yakaderera tembiricha yekushisa kuvhunduka kuyedzwa.
Mwero wekudziya/kutonhora hausi pasi pe30℃/miniti.
Iyo tembiricha shanduko yemhando yakakura kwazvo, uye kuomarara kweyedzo kunowedzera nekuwedzera kweiyo tembiricha yekuchinja.
Musiyano uripo pakati peye tembiricha yekuvhundutsa bvunzo uye tembiricha kutenderera bvunzo ndiyo inonyanya kusiyanisa yekuremerwa kushushikana meshini.
Iyo tembiricha yekuvhundutsa bvunzo inonyanya kuongorora kutadza kunokonzerwa nekudonha uye kuneta kukuvara, nepo tembiricha kutenderera ichinyanya kuongorora kutadza kunokonzerwa nekuveura kuneta.
Iyo tembiricha yekuvhundutsa bvunzo inobvumira kushandisa maviri-slot test mudziyo; tembiricha kutenderera bvunzo inoshandisa imwe-slot test mudziyo. Mune maviri-slot bhokisi, tembiricha yekuchinja inofanirwa kunge yakakura kupfuura 50 ℃/miniti.
Zvinokonzeresa tembiricha kuvhunduka: yakanyanya kushanduka tembiricha panguva yekugadzira uye kugadzirisa maitiro senge reflow soldering, kuomesa, kugadziridza, uye kugadzirisa.
Maererano neGJB 150.5A-2009 3.1, kupisa kwekushisa ishanduko yakapinza mumhepo yekushisa yemidziyo, uye kuchinja kwekushisa kunodarika 10 degrees / min, inova kupisa kwekushisa. MIL-STD-810F 503.4 (2001) inobata maonero akafanana.
Pane zvikonzero zvakawanda zvekuchinja kwekushisa, izvo zvinotaurwa mumazinga akakodzera:
GB/T 2423.22-2012 Environmental Testing Chikamu 2 Muedzo N: Kuchinja kweTembiricha
Mamiriro emumunda ekuchinja kwetembiricha:
Kuchinja kwekushisa kwakajairika mumidziyo yemagetsi uye zvikamu. Kana iyo midziyo isingabatidzwe, zvikamu zvayo zvemukati zvinonzwa zvishoma nezvishoma kuchinja kwekushisa pane zvikamu zvekunze kwayo.
Kukurumidza kuchinja kwekushisa kunogona kutarisirwa mumamiriro ezvinhu anotevera:
1. Kana iyo michina inotamiswa kubva munzvimbo inodziya yemukati kuenda kunzvimbo inotonhora yekunze, kana zvinopesana;
2. Kana iyo midziyo inoratidzwa kunaya kana kunyudzwa mumvura inotonhora uye kamwe kamwe inotonhorera pasi;
3. Yakaiswa mumidziyo yekunze yemhepo;
4. Pasi pezvimwe zvekufambisa uye kuchengetedza mamiriro.
Mushure mekushandisa simba, tembiricha yakakwira gradients inogadzirwa mumidziyo. Pamusana pekushanduka kwekushisa, zvikamu zvichasimbiswa. Semuyenzaniso, padhuze ne-high-power resistor, mwaranzi ichaita kuti kupisa kwepamusoro kwezvikamu zviri pedyo kukwire, nepo zvimwe zvikamu zvichiramba zvichitonhora.
Kana iyo yekutonhodza ichibatidzwa, zvinhu zvakatonhodzwa zvekugadzira zvinosangana nekuchimbidzika kwetembiricha. Kukurumidza kushanduka kwekushisa kwezvikamu zvinogonawo kukonzerwa panguva yekugadzira michina. Nhamba uye hukuru hwekushanduka kwekushisa uye nguva yenguva yakakosha.

3.2 Kushandisa:
3.2.1 Nzvimbo Yakajairika:
Muedzo uyu unoshanda kumidziyo inogona kushandiswa munzvimbo idzo tembiricha yemhepo inogona kuchinja nekukurumidza. Muedzo uyu unongoshandiswa kuongorora mhedzisiro yekuchinja kwekushisa nekukurumidza pane yekunze yemidziyo, zvikamu zvakaiswa pamusoro pekunze, kana zvikamu zvemukati zvakaiswa padyo nekunze. Mamiriro ezvinhu akafanana anotevera:
A) Iyo midziyo inotamiswa pakati penzvimbo dzinopisa uye yakaderera tembiricha nharaunda;
B) Inosimudzwa kubva pasi yakakwira tembiricha nharaunda kusvika pakakwirira (inongopisa ichitonhora) nemutakuri wepamusoro-soro;
C) Paunenge uchiyedza zvinhu zvekunze chete (kurongedza kana zvishandiso zvepasi), inodonhedzwa kubva kune inopisa ndege inodzivirira goko pasi pehupamhi hwepamusoro uye yakaderera tembiricha mamiriro.
3.2.2 Chengetedzo uye Yezvakatipoteredza Stress Kuongorora:
Pamusoro pezvinotsanangurwa mu3.3, bvunzo iyi inoshanda kuratidza nyaya dzekuchengetedza uye hurema hunogona kuitika kazhinji kana mudziyo uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchi . muganhu wemidziyo). Kunyangwe bvunzo iyi ichishandiswa seyezvakatipoteredza stress screening (ESS), inogona zvakare kushandiswa seyekuongorora bvunzo (uchishandisa tembiricha yekushisa kwakanyanya kwakanyanya) mushure mekurapa kwakakodzera kweinjiniya kuratidza hurema hunogona kuitika kana midziyo yaiswa mumamiriro ezvinhu. yakaderera kupfuura kupisa kwakanyanya.

4.1.2 Mamiriro Ezvakatipoteredza:
Kutyisa kwekushisa kunowanzova nemigumisiro yakakomba pane chikamu chiri pedyo nechekunze kwechigadzirwa. Iyo iri kure kure nekunze kwekunze (zvechokwadi, inoenderana nehunhu hwezvinhu zvakakosha), inononoka kushanduka kwekushisa uye zvishoma zviri pachena mugumisiro. Mabhokisi ekufambisa, kurongedza, nezvimwe zvichaderedzawo kukanganiswa kwetembiricha pamidziyo yakavharirwa. Kukurumidza kushanduka kwetembiricha kunogona kukanganisa kushanda kwemidziyo kwenguva pfupi kana zvachose. Iyi inotevera mienzaniso yezvinetso zvinogona kumuka kana midziyo yaiswa munzvimbo yekuvhundutsa tembiricha. Kufunga nezve anotevera akajairwa matambudziko anozobatsira kuona kana bvunzo iyi yakakodzera midziyo iri pasi pekuyedzwa.
A) Mamiriro chaiwo emuviri ndeaya:
1) Kupwanya kwemidziyo yegirazi uye zviridzwa zvemaziso;
2) Yakanamira kana yakasununguka zvikamu zvinofamba;
3) Kutsemuka mumapellets akasimba kana makoramu mune zvinoputika;
4) Yakasiyana shrinkage kana kuwedzera mwero, kana induced kuomarara kwemitengo yezvinhu zvakasiyana;
5) Deformation kana kuputika kwezvikamu;
6) Kuputika kwepamusoro pekuvhara;
7) Kudonha mumakamuri akavharwa;
8) Kukundikana kwekudzivirira kwekudzivirira.
B) Yakajairika makemikari mhedzisiro ndeaya:
1) Kuparadzaniswa kwezvikamu;
2) Kukundikana kwekuchengetedzwa kwemakemikari reagent.
C) Mamiriro emagetsi akajairika ndeaya:
1) Kuchinja kwemagetsi nemagetsi zvikamu;
2) Kukurumidza kunyungudutswa kwemvura kana chando kuchikonzera kutadza kwemagetsi kana kwemagetsi;
3) Yakawandisa static magetsi.
Chinangwa chetembiricha yekuvhundutsa bvunzo: Inogona kushandiswa kuwana dhizaini yechigadzirwa uye kukanganisa maitiro panguva yeinjiniya nhanho yekuvandudza; inogona kushandiswa kuonesa kuchinjika kwezvigadzirwa kune tembiricha yekuvhundutsa nharaunda panguva yekupedzisa chigadzirwa kana dhizaini yekuzivikanwa uye matanho ekugadzirwa kwehuwandu, uye nekupa hwaro hwekupedzisa dhizaini uye sarudzo dzekugamuchira kugadzirwa kwakawanda; kana ichishandiswa sekutarisa kushushikana kwezvakatipoteredza, chinangwa ndechekubvisa kutadza kwechigadzirwa chekutanga.
