Ichi chinyorwa chinozogovera matekiniki akadai sekurongeka, kugadzirisa, uye warping board test mukubhururuka probe test mashandiro ekutarisa chete.
1. Counterpoint
Chinhu chekutanga kutaura pamusoro pacho kusarudzwa kwezvipikisi. Kazhinji, maburi maviri chete diagonal anofanirwa kutorwa seanopikisa. ?) Usafuratira IC. Zvakanakira izvi ndezvekuti pane mashoma ekurongeka mapoinzi, uye shoma nguva inoshandiswa pakurongeka. Kazhinji kutaura, etching inogara iine undercuts, saka haina kunyatso kurongeka kusarudza mapedhi ekumisikidza mapoinzi. Kana paine akawanda akavhurika maseketi, haufanirwe kumira nekukurumidza, uye mira kana yakavhurika yedunhu bvunzo yapera uye wotanga pfupi dunhu bvunzo, nekuti iwe unogona kutoona zvikanganiso zvakavhurika zvedunhu panguva ino, unogona. wedzera nzvimbo yakanangwa zvinoenderana neyakashumwa nzvimbo yekukanganisa.
Ngatitaure nezve kurongeka kwemaoko zvakare. Kunyatsotaura, maburi haasi pakati pemapadhi, saka kana uchiisa, dots inofanira kuiswa pakati pemapadhi zvakanyanya sezvinobvira, kana kuedza kuwirirana nemakomba chaiwo? Kazhinji kana paine akawanda mapoinzi ekuedzwa Kune gomba, sarudza yekupedzisira. Kana iri yakawanda IC, kunyanya kana IC ichiwanzoita manyepo akazaruka dunhu, unofanirwa kuisa gomba rekugadzirisa pakati pedhi.
Chechipiri, yakagadziriswa furemu
Iyo yakagadziriswa furemu ndiyo yakagadziriswa test bracket. Iyo data yakagadzirwa inomiririrwa nemabhokisi maviri. Furemu yekunze ndiyo furemu. Kune bhodhi rakadaro, saizi yakapihwa nemushini inogona kushandiswa zvakananga. Kune iyo data isina furemu, Inomiririrwa nebhokisi. Isu tinogona kushandisa iyo show board command (iyo ichashandiswa kana tichitarisa kudivi rebhodhi) kuona kuti ndeipi padhi inoedzwa pamucheto wepedyo. Enzanisa nebhodhi chaiyo kuti uone kureba kwayo kubva kumucheto Mari yakawanda inoshandiswa kubhadhara.
3. Kuyambuka
Kune patch board, iyo yakasarudzwa inogona kuongororwa. Isu tinogona kushandisa basa iri kuona kuyedzwa kwechigamba bhodhi uko chinhambwe chiri pakati pepadhi uye bhodhi mupendero idiki kwazvo kuyedza. Iyo nzira ndeyekuvhara mapedhi asingakwanisi kubatwa netireyi. Muedzo mumwe chete unoyambuka, uye mushure mekuedzwa, tireyi inoiswa pane yakagadzika ndiro yeyakaedzwa imwe chete, uye bhodhi isina kuongororwa nguva yekupedzisira inosarudzwa, kuitira kuti bhodhi rose riongororwe ne2 bvunzo. Naizvozvo, isu tinofanirwa kushandisa zvakachinjika mabasa anopihwa nemidziyo kuzadzisa zvimwe zvakakosha zvinodiwa.
Chechina, warpage
Saizi mune imwe nzira yakakurisa, kunyanya kana saizi mune imwe nzira iri diki, bhodhi rinongotenderera (rakakonzerwa negiravhiti) kana raiswa pamushini wekuyedza, uye muchina wedu unobhururuka wekuongorora une chimiro chidiki Dambudziko diki, saizi mugwara reX yakakura, asi pallet imwe chete inoiswa, uye munzira yeY ine saizi diki, mapallet matatu anogona kuiswa. Nokudaro, muchina wacho unosarudza kureba kwebhodhi kuti kuyerwa Kana yaiswa kune X nhungamiro yemuchina, zviri nani kuironga nemaoko, kutenderedza bhodhi 90 madhigirii, uye kuisa kutungamira kwayo kwakareba munzira yeY, iyo inogona kugadzirisa dambudziko rebhodhi warpage muyedzo kune imwe nhanho. (Kugadziridza uku kunofanirwa kubatwa muDPS).
