e pei o le PCB Faʻaaogaina e eseese eletise meafaigaluega avea atili ma sili atu faigata, mauaina o le sese o PCB backplane lima e le gata e faigata ae faʻapea foi ma maualalo faʻatuatuaina. O le AUTOMATIC tester mo PCB backplane faʻavae i luga o le PLD faʻalauiloaina i lenei pepa mafai ona faʻaleleia atili le galue lelei ma faʻamautinoa le faʻamaoniaina faʻatuatuaina.

Faatasi ai ma le televave atinae o le faaeletonika tekonolosi, ua lautele faaaogaina i eseese ituaiga o eletise masini gaosiga o lolomi laupapa matagaluega (PCB) faateleina tele, tagata faigaluega tomai faapitoa e vave fuafuaina le tua i luga o le puupuu matagaluega, matala matagaluega sese poʻo le faʻasaʻoina o le aofaʻi tele o teteʻe, pe a faʻalagolago i le faʻamaonia mauaina e matua faigata, ma le faʻatuatuaina e maualalo, o lea la le matagaluega laupapa i tua tele faʻateleina manaoga o otometi suʻega. I lenei pepa, o se metotia o otometi suʻega faiga mo PCB backplane faʻavae i luga o EPM7128 pulea multiway sui filifilia ADG732 ua fautuaina, ma o lona faʻatinoina ua tuuina atu. Ua faʻamaonia o le suʻega metotia e vave ma aoga pe a maeʻa ona faʻaaogaina i le PCB backplane test.

O le faiga faʻavae o otometi suʻesuʻe o loʻo faʻaalia i le Ata 1, lea e aofia ai microcomputer, USB pasi DIO interface card, PLD poloka poloka, tele-ala filifiliga ki, tofotofoga totoga ma isi.O le faiga e mafai ona vave suʻesuʻe matala ma puʻupuʻu matagaluega sese o nofofua, lua ma multilayer PCB pito i tua.

E leai ni manaʻoga faʻapitoa a le Microcomputers, ma e masani ona faʻaaoga komepiuta masani. O le system interface e faʻaaogaina le taugofie USB-7802ADIO alamanuia faʻataʻitaʻiga faʻataʻitaʻiga gaosia e Hongtop Fuataga ma Pulea Tekonolosi Co., LTD. O le sao ma galuega faatino volitiga o 0 ~ 5V, i laina ma USB pasi + 5V tulaga masani. Usb-7802a o le 32-auala faʻafuainumera TTL tulaga maualuga sao / laupapa faʻatinoina, ma 4 8-bit faʻatulagaina sao sao ma 4 8-bit faʻafuainumera latch uafu, o le aofaʻi o 32 inputs ma 32 galuega faatino; Faʻaavanoaina win95 / 98/2000 / NT i lalo ole polokalame suʻega ma le polokalama fesoʻotaʻi malosi (DLL).Talu ai o le USB pasi, o le USB protocol otometi lava ona tofia le faʻavae tuatusi o le laupapa.
