Multi-circuit boards |Gungano uye welding mhando |welding cracks |pad shedding

Maitiro ekuve nechokwadi chekusangana uye welding mhando yemabhodhi e-multi-circuit board uye kudzivirira kutsemuka kwemagetsi uye matambudziko ekudurura mapadhi?

Sezvo kudiwa kwemidziyo yemagetsi kuri kuramba kuchikura, kudiwa kweakavimbika uye emhando yepamusoro mabhodhi ematunhu mazhinji kwave kunetsa.Aya mapuranga ematunhu anoita basa rakakosha pakuita kuti midziyo yemagetsi ishande zvakanaka.Zvisinei, panguva yegungano uye welding maitiro e-multi-layer circuit boards, kana asina kubatwa zvakanaka, zvinetso zvakadai sekuputika kwekuputika uye pedhi peeling zvinogona kuitika.Mune ino blog post, isu tichakurukura nzira dzinoshanda dzekuve nechokwadi chemhando ye-multi-circuit board assembly uye soldering uye kudzivirira matambudziko aya kuti asaitike.

Capel ikambani ine makore gumi nemashanu eruzivo rweprojekiti uye tekinoroji yeindasitiri yehunyanzvi.Nechikwata chakasimba uye chakanakisa otomatiki michina, vava mugadziri akavimbika muindasitiri iyi.Maitiro avo akaomarara uye epamusoro ekugadzira akasanganiswa nehunyanzvi hwekuita maitiro anovagonesa kugadzira emhando yepamusoro, akawanda-anoshanda edunhu mabhodhi.

Kuti uve nechokwadi chemhando yekusangana uye welding ye multilayer circuit board, anotevera matanho anokosha anofanira kuteverwa:

1. Sarudza chinhu chakakodzera:Kusarudzwa kwezvinhu kwakakosha pakusarudza huwandu hwese hwebhodhi redunhu.Sarudza zvigadzirwa zvemhando yepamusoro zvinosangana nezvinodiwa.Izvi zvichabatsira kudzivirira matambudziko anoenderana ne solder cracks uye pad detachment.

2. Kudzora kunaka padanho rega rega:Shandisa yakasimba yemhando yekutonga system inovhara yega yega nhanho yekugadzira maitiro.Izvi zvinosanganisira kuongorora zvinhu zvinopinda, kutarisa maitiro ekugadzira uye kunyatsoyedza chigadzirwa chekupedzisira.Kugara uchiongorora kunogona kubatsira kuona chero hurema kana matambudziko nekukurumidza, kuderedza mukana wekutsemuka kwe solder uye debonded pad matambudziko.

3. Kuchengetedza uye kubata kwakakodzera:Kuchengetedza kwakakodzera uye kubata kwemapuranga edunhu kunokosha pakuchengetedza kuvimbika kwavo.Ita shuwa kuti mabhodhi edunhu anochengetwa munzvimbo inodzorwa ine hunyoro hwakakwana uye tembiricha.Vabate nemazvo kuti vadzivise chero kukuvara kwemuviri kunogona kukonzera kutsemuka kwe solder kana mapedhi kudonha.

4. Magadzirirwo nemarongerwo akarurama:Tevedza indasitiri yakajairwa dhizaini uye marongero nhungamiro kuti uve nechokwadi chekushanda kwakanaka uye kuvimbika kwebhodhi.Chimiro chakanyatsogadzirwa chinogona kuderedza kushushikana kwezvikamu panguva yegungano uye welding, nokudaro kuderedza mukana wekutsemuka kana kuputika.

5. Nzira dzakanakisisa dzegungano:Shandisa nzira dzakakodzera dzekuunganidza dzinoenderana nezvinodiwa zvebhodhi.Funga zvinhu zvakadai sechikamu chechikamu, nzira yekutengesa uye reflow profile kuti ive nechokwadi chekubatana kwakasimba uye kwakavimbika.Kudzora kwakaringana tembiricha panguva yewelding kwakakosha kudzivirira kutsemuka nekusvuura.

6. Kuedza kwakakwana:Kuongororwa kwakadzama kwebhodhi redunhu rakaungana kuti rione kushanda kwayo uye kunaka.Izvi zvinosanganisira kuedza kwemagetsi, kuongorora kushanda uye kuvimbika kuedza.Kuedza kunobatsira kuona chero nyaya dzinogona kuitika panguva yekuungana nekutengesa saka matanho ekugadzirisa anogona kutorwa bhodhi risati rasvika kumushandisi wekupedzisira.

Nekutevedzera iyi nhungamiro, vagadziri vanogona kuvandudza zvakanyanya kunaka kweakawanda-bhodhi musangano uye solder.Capel's rigorious approach to circuit board experience inova nechokwadi chekuti maitiro avo ekugadzira akagadziridzwa kuti abudise emhando yepamusoro mabhodhi edunhu uye kuderedza mukana wekutsemuka kwekutengesa uye nyaya dzepedhi.

Muchidimbu,kuve nechokwadi chehutano hwekuunganidza uye kutengesa kwemapuranga ematunhu akawanda kwakakosha pakuita kwese uye kuvimbika kwemidziyo yemagetsi.Nekutevera matanho ari pamusoro uye kusarudza mugadziri ane mukurumbira ane ruzivo senge vagadziri veCapel vanogona kudzikisa njodzi yekutsenga kuputika uye pad detachment.Kuisa mari mumidziyo yemhando yepamusoro, kushandisa masisitimu akasimba ekudzora mhando, uye kushandisa nzira dzekuunganidza dzakakosha pakugadzira mabhodhi edunhu akavimbika uye akasimba.
