Ubugenzuzi bwa PCB

Ibipimo byubugenzuzi bwumuzunguruko

1. Ingano irakwiriye kugenzurwa ryinjira rya terefone igendanwa ya HDI yumuzunguruko.

2. Gahunda y'icyitegererezo igomba kugenzurwa hakurikijwe GB2828.1-2003, urwego rusange rw'ubugenzuzi II.

3. Igenzura rishingiye kubikoresho bya tekiniki yibanze hamwe nicyitegererezo.

4. Urwego rwujuje ubuziranenge rushingiye ku gaciro ka AQL: Icyiciro A = 0.01, Icyiciro B = 0,65, Icyiciro C = 2.5.

5 ubushyuhe burigihe ferrochrome.

6 , ibikoresho bivanze, nta Package yuzuye.

1 Raporo yoherejwe ntabwo yatanzwe.Raporo yoherejwe ku ruganda

2. Ibintu byubugenzuzi muri raporo yoherejwe n’abakora ibicuruzwa ntabwo bihuye kandi byuzuye ukurikije ibisabwa by’ubugenzuzi, amakuru yikizamini ntabwo yujuje ibyangombwa bisanzwe, raporo ntiyemerwa n’umugenzuzi w’ubuziranenge cyangwa abakozi bo mu rwego rwo hejuru, na raporo. ibirimo ni ibinyoma, nibindi Niba ibisabwa haruguru bitujujwe.B urutonde rwibintu byagenzuwe Ibintu rusange bisobanura inenge Ibikoresho byinjira biratandukanye nuwabikoze ntangarugero, nimero ya plaque itandukanye, isahani itandukanye (harimo no kutamenyekanisha isahani), nta cyerekezo cy’ibicuruzwa, kandi nta ruganda rukora.Ntabwo hagomba kubaho impande zikarishye zikikije PCB kugirango zigire ingaruka ku nteko no kwangiza uyikora.Ibibyimba binini kandi bike Ibinini binini kandi bito (ukurikije ibisabwa mu bishushanyo mbonera) Hariho umuringa usigaye mu mwobo wa NPTH, kandi hari umwobo mu mwobo.) yarangije aperture: niba irenze ibisabwa hepfo

3 Gucukura umwobo uzengurutse: NPTH: +/- 2mil (+/- 0.05mm);NPTH: umwobo wumuringa B utarohama;PTH: kurohama umwobo wumuringa PTH: +/- 3mil (+/- 0.075mm) 2,
