Laupapa matagaluega Lolomiina: faamatalaga, igoa

O le laupapa matagaluega lomia o se elemene fausaga e aofia ai a conductors dielectric faavae ma le kopa, ua teuina i luga o se substrate i le pepa faatumu o fuaiupu metallized. E maua ai se lotoa o elemene faaeletoroni matagaluega.

O le laupapa matagaluega ua i ai se aofai o tulaga lelei faatusatusa i le tele (faalagolago) faapipiiina le faaaogaina o uaea ma uaea:

• mounting density maualuga o le vaega o le leitio ma o latou tuufaatasi, e mafua i matua faaitiitia tele ma le mamafa;
• mauaina conductors ma puipuia o luga, ma elemene faʻaratiasia i se faataamilosaga faatekinolosi e tasi;
• mautu, repeatability uiga e pei o capacitance, conductance, inductance;
• saosaoa maualuga ma circuitry puipuiga mausali leo;
• tetee atu i faatosinaga masini ma climatic;
• standardization ma soʻofaʻatasiga fofo o faafitauli faatekonolosi ma mamanu;
• fonotaga faatuatuaina, iunite tau ma le masini o se atoa;
• faaleleia processability o se taunuuga o faigata faʻaautomatika o gaoioiga faapotopotoga, pulea ma le fetuunaiga o gaoioiga;
• maualalo le mamafa o galuega, mea taumafa ma tau.

Le lomia matagaluega laupapa ei ai foi drawbacks, ae ua fai si: faatapulaaina maintainability ma le lavelave maualuga o le faaopoopoina o suiga mamanu.

O elemene o sea pepa aofia ai se faavae dielectric, o se ufiufi apamemea, lea o se mamanu o conductors lomia, moa fesootaiga; faatulagaina ma mounting pu.

Manaoga e faatatau i nei oloa GOST

• Lolomiina e tatau ona i ai se lanu homogeneous laupapa matagaluega i le substrate dielectric e avea monolithic i fausaga, e le o aofia vesicles lotoifale, ua goto ifo, inclusions fafo, mavetevete, chips, fusi. Ae peitai faatagaina tasi maosiosia, inclusions uamea, le aveesea o sailia neprotravlennogo tasi vaega ma faaaliga o le faatulagaga lea e le suia le faataamilosaga i le eletise o le oloa, e le faaitiitia le mamao faatagaina le va o le elemene mamanu.
• Ata - manino, i se pito lamolemole, e leai se pāpā, mavetevete, peeling, meafaigaluega Lolomi. Laitiiti stains le lotoifale, ae le sili atu i le lima ni manatu i le sikuea decimeter, faatasi ai ma le aiaiga o le a tutusa le vaega o totoe o le lautele ala i le faatagaina maualalo; taʻe umi i le ono millimeters ma le loloto o le 25 microns.

Ina ia faaleleia le corrosion faatinoga ma faaleleia solderability luga laupapa coated e tuufaatasiga electrolytic lea e tatau ona faaauau pea, e aunoa ma peeling, malologa ma podgarov. Faatulagaina ma e tatau ona lafoaia pu mounting o e tusa ai ma le ata. Faatagaina o ia e maua se palasi faamatalaina totogifuapauina vasega saʻo. Ina ia faaleleia ai le faatuatuaina o soldering i luga o luga i totonu uma o mounting pu sausauina vaega apamemea, o lona mafiafia e tatau ona itiiti ifo i lo le 25 microns. E taʻua lenei faagasologa - metallization o pu.

O le a le vasega PCB? I lalo o lenei manatu e faatatau vasega tonu laupapa matagaluega o fale gaosi oloa, o loo latou tuuina atu e GOST 23751-86. E faalagolago i le mamanu density o le laupapa matagaluega lomia e lima o vasega o le sao atoatoa, le filifiliga o lea ua fuafuaina e le meafaigaluega faapitoa o le tulaga o pisinisi. O le vasega muamua ma le lua e le manaomia ai meafaigaluega tonu ma ua manatu taugofie e maua. O le vasega fa ma le lima e manaomia ai mea faapitoa, meafaigaluega faapitoa, le mama atoatoa i le gaosiga o oloa, malulu ea, pulea vevela. vaega tele fua pisinisi Atunuu lomia laupapa matagaluega o le vasega lona tolu o sao atoatoa.
