Fa'amanuiaga
1) Tausaga o le poto masani i le gaosiga o le afa-pu, faʻaaogaina le Da Chuan Routing machine, faʻataʻitaʻiina le afa-pu ma faʻataʻitaʻiina foliga, faʻafeiloaʻi maʻoti foliga manaʻomia;
2) Laiti laina lautele ma laina vaeluaga: 0.065/0.065mm, laʻititi BGA pad: 0.2mm, faʻafeiloaʻi manaoga faapitoa o tagata faatau;
3) Electroplated Copper Flling of Blind Holes by Universal DVCP(Double Track Vertical Continuous Copper Plating Equipment) ina ia mautinoa e leai ni avanoa i pu ma le lelei o oloa a tagata faatau;
4) Fa'ata'ita'iga fa'ata'ita'iga fa'ata'ita'iga fa'ata'ita'iga fa'ata'ita'iga, fa'amautu oloa fa'atau oloa.

O la matou auala fou e mafai ai ona matou tuʻufaʻatasia le antenna ma faʻailoga faʻailoga i totonu o se afifi e tasi, faʻaumatia luʻitau tuʻufaʻatasia.E le gata o lenei mea e faʻasaoina ai oe taimi ma taumafaiga, e faʻamautinoa ai foʻi ala faʻailoga pupuu, faʻaitiitia le leiloa o faʻailoga i le taimi o le faʻasalalauga ma le gaioiga.
Fa'ata'ita'iina ma le fa'aeteete mai mea e sili ona lelei, o matou laupapa PCBA o lo'o faia i le Fr-4, o se mea fa'atuatuaina ma le umi e iloa mo ona mea lelei eletise ma le malosi fa'ainisinia.O le laupapa e 6 laulau, e maua ai le tele o avanoa mo vaega uma e manaʻomia aʻo faʻatumauina galuega sili ona lelei.
O matou laupapa PCBA e 1.2 mm mafiafia, faʻamautinoaina le maualuga maualuga ma le faʻaogaina lelei i totonu o lau faʻaoga saogalemu.0.102mm/0.1mm la'ititi la'ititi i fafo ma fua fa'avanoa e maua ai le sa'o maualuga mo le fa'atinoga sili i faiga saogalemu.
O pu eliina ma le laʻititi laʻititi o le 0.1 mm e faʻaleleia atili ai le faʻaogaina o le PCB ma le fetaui ma masini saogalemu eseese.Matou te fa'aogaina se fale'ie e ala i le fa'agasologa e puipui ai pu ua viliina mai le fa'aleagaina ma fa'amautinoa feso'ota'iga fa'atuatuaina i le va o laulau eseese o le laupapa.
Ina ia faʻamautinoa le ola tautua ma le faʻamaoni o le laupapa PCBA, matou te faʻaogaina le faʻaofuofu nickel electroless auro (ENIG) mo togafitiga luga.O lenei togafitiga i luga e maua ai kemikolo sili ona lelei ma le eletise, puipuia le pala ma faʻamautinoa le lelei o le faʻasalalauina o faailoilo.
Fa'alagolago i lo matou tomai ma le poto masani i le gaosiga o mea tau eletise.Matou te tuuto atu i le tuʻuina atu o oloa maualuga e fetaui ma manaʻoga faʻapitoa o le alamanuia saogalemu.Fa'aagaga i la matou laupapa PCBA saogalemu fa'aeletonika e tasi ma iloa le tu'ufa'atasiga lelei, mamanu fa'apitoa ma le fa'atinoga sili atu.
