Choyesa singano chowuluka sichitengera mtundu wa pini womwe umayikidwa pazitsulo kapena bulaketi.Kutengera dongosololi, ma probe awiri kapena kuposerapo amayikidwa pamitu yaying'ono, yoyenda mwaulere mu ndege ya xy, ndipo zoyeserera zimayendetsedwa mwachindunji ndi CADI. Gerber data.Zofufuza zapawiri zimatha kuyenda mkati mwa 4 mil wina ndi mzake.Zofufuza zimatha kuyenda modzidzimutsa, ndipo palibe malire enieni a momwe angayandikire wina ndi mzake.Woyesa ndi manja awiri osunthika amachokera ku miyeso ya capacitance.The bolodi la dera limayikidwa mwamphamvu pazitsulo zotetezera pazitsulo zachitsulo zomwe ZOCHITIKA ngati mbale ina yachitsulo ya capacitor.Ngati pali dera lalifupi pakati pa mizere, mphamvuyo idzakhala yaikulu kusiyana ndi nthawi inayake.Ngati pali kupuma, mphamvu idzakhala yaying'ono.

Liwiro la mayeso ndilofunika kwambiri posankha woyesa.Ngakhale woyesa bedi la singano akhoza kuyesa molondola masauzande ambiri a mayesero panthawi imodzi, woyesa singano wowuluka akhoza kuyesa mfundo ziwiri kapena zinayi panthawi imodzi.Kuonjezera apo, kuyesa kamodzi ndi woyesa singano pabedi angagule 20-305 yekha, kutengera zovuta za bolodi, pomwe woyesa singano wowuluka amafunikira Ih kapena kupitilira apo kuti amalize kuyesa komweko.Shipley (1991) adalongosola kuti njira iyi ndi yabwino kwa opanga matabwa ozungulira ovuta omwe ali ndi zokolola zochepa, ngakhale opanga mapepala apamwamba osindikizira amalingalira kuti njira yoyesera pini yoyendayenda ikuchedwa.

Poyesa mbale zopanda kanthu, pali zida zoyesera zodzipatulira (Lea, 1990) .Njira yotsika mtengo ingakhale yogwiritsira ntchito chida chapadziko lonse, ngakhale kuti poyamba chinali chokwera mtengo kuposa chida chodzipatulira, mtengo wake woyamba ukhoza kuchepetsedwa ndi kuchepetsa mtengo wa masinthidwe amunthu payekha.Kwa ma gridi azinthu zambiri, gridi yokhazikika ya matabwa ndi zida zapamtunda zokhala ndi ma pini ndi 2.5 mm.Panthawiyi mayeso oyeserera ayenera kukhala akulu kuposa kapena ofanana ndi 1.3mm.

Kwa gridi ya Imm, pepala loyesera lapangidwa kuti likhale lalikulu kuposa 0.7mm.Ngati gululi ndi laling'ono, pini yoyesera ndi yaing'ono, yowonongeka, komanso yowonongeka.Choncho, ndi bwino kugwiritsa ntchito ma grids akuluakulu kuposa 2.5mm.Crum (1994b) adanena kuti kuphatikiza kwa tester universal (standard grid tester) ndi choyesa singano chowuluka chikhoza kupangitsa kuzindikira kwa gulu laling'ono laling'ono kuti likhale lolondola komanso lopanda ndalama. mfundo zomwe zimapatuka ku gridi.Komabe, kutalika kosiyanasiyana kwa mapadi omwe amachitiridwa ndi mpweya wotentha kumalepheretsa kulumikizana kwa mayeso.
Magawo atatu otsatirawa amazindikiridwa nthawi zambiri:
1) kuzindikira mbale wamaliseche;
2) kuzindikira pa intaneti;
3) kuzindikira ntchito.
The general type tester angagwiritsidwe ntchito kuzindikira mtundu wa kalembedwe ndi mtundu wa board board komanso ntchito zapadera.
Zopaka zitsulo zofala ndi:
Mkuwa
Tini

Kuchuluka kwake kumakhala pakati pa 5 ndi 15 cm
Aloyi ya lead-tin (kapena tini-copper alloy)
Ndiye kuti, solder, nthawi zambiri 5 mpaka 25 m wandiweyani, wokhala ndi malata pafupifupi 63%

golidi: Nthawi zambiri amangokutidwa pa mawonekedwe

siliva: Nthawi zambiri amangokutidwa pa mawonekedwe, kapena yonseyo ndi aloyi wasiliva
