Ehe. Simbi isingatsvi 304 inogona kusungirirwa zvakanaka kumhangura mu vacuum uchishandisa mhando dzakasiyana-siyana uye makemikari anowedzera kusungirirwa (BFM). Simbi dzinozadza dzakavakirwa pagoridhe, sirivha uye nickel dzinogona kushanda. Sezvo mhangura ichikura zvishoma kupfuura simbi isingatsvi 304, kutarisisa kwakakosha kunofanirwa kupihwa kune connection configuration. Muchiitiko ichi, simba remhangura richave rakaderera kwazvo, saka inogona kukwana simbi isingatsvi pasina deformation inoonekwa.
Zvigadzirwa zvesimbi zvinowanzo shandiswa pakupisa kunosvika 4° Kelvin. Pane zvinhu zvinofanirwa kugadziriswa uye zvisingakwanisike, asi simbi dzesimbi dzinoshandiswa mugoridhe nesirivha ndidzo dzinowanzo shandiswa pakushandisa uku.
3. Ndinoda kusonera zvinhu zvakaoma, asi handizivi kuti ndingasonera zvinhu zvose panguva imwe chete sei. Zvinokwanisika here kusonera zvinhu zvine matanho akawanda?
Ehe! Nyanzvi yekupa soldering inogona kuronga nzira yekusoldering ine matanho akawanda. Funga nezvezvinhu zvekutanga neBFM kuitira kuti solder joint yekutanga isanyunguduke mumatanho anotevera. Kazhinji, kutenderera kwekutanga kunomhanya patembiricha yakakwira kupfuura kutenderera kunotevera uye BFM hainyunguduke mumatanho anotevera. Dzimwe nguva BFM inoshanda zvakanyanya mukupararira kwezvimisikidzo mu substrate zvekuti kudzokera kutembiricha imwecheteyo hakukonzere kunyunguduka. Kusoldering ine matanho akawanda kunogona kuva chishandiso chiri nyore uye chinoshanda pakugadzira zvinhu zvinodhura zvekurapa.
Dambudziko iri rinogona kugadziriswa! Pane nzira dzekudzivirira izvi, nzira inoshanda zvikuru ndeyekushandisa huwandu hwakakodzera hweBFM. Kana joini iri diki uye iri diki munzvimbo, zvingaita sezvinoshamisa kuti BFM yakawanda sei inodiwa kuti joini ishande zvakanaka. Verenga nzvimbo yecubic yejoini uye edza kushandisa BFM yakawanda zvishoma pane nzvimbo yakaverengerwa. Dhizaini yekubatanidza inobhurwa i socket yakaboorwa yakafanana ne tube ID, zvichibvumira BFM kufamba zvakananga ku tube ID ne capillary action. Siya nzvimbo pamagumo e tube kudzivirira capillary action, kana kugadzira joini kuitira kuti tube ibude zvishoma kupfuura joini. Nzira idzi dzinoita kuti BFM ifambe kusvika kumagumo e pombi, nokudaro zvichideredza njodzi yekuvharika.
Nyaya iyi inouya nguva nenguva uye inoda kukurukurwa. Kusiyana nemafillets e solder, ayo anogadzira simba mujoini, mafillets makuru e solder haaparadzi BFM uye anogona kukuvadza. Chinokosha ndechekuti chii chiri mukati. Mamwe ma PM anoomarara mufillets makuru nekuda kwekuwanda kwezvikamu zvisinganyungudike zvakanyanya. Muchiitiko ichi, kunyangwe paine kuneta kudiki, fillet inogona kutsemuka uye kukura kusvika yakundikana zvakanyanya. Pakusungirirwa, kuvapo kudiki, kunoramba kuripo kweBFM panzvimbo yejoini inowanzova ndiyo nzira yakakodzera yekutarisa nemaziso.
