Technological advances ensure that tejede Circuit ọkọ ko le ṣe awọn iṣẹ eka nikan, ṣugbọn tun le ṣe iṣelọpọ ni idiyele. Eyi ni pato idi ti PCBS jẹ apakan pataki ti ọpọlọpọ awọn ẹrọ.

Idiwọn IPC

Tejede Circuit Board Association (kosi awọn sepo ká tẹlẹ orukọ; Although retaining the IPC name, it is now known as the Association connected Electronics Industry Association, a global trade association for the manufacture of PCB and other electronic components. Ile-ẹkọ naa ti da ni ọdun 1957 ati awọn iṣedede atẹjade fun itẹwọgba ti awọn igbimọ Circuit ti a tẹjade.

Ologun ati Aerospace

Ile-iṣẹ Ọkọ ayọkẹlẹ

Awọn ohun elo ile-iṣẹ

Awọn ẹrọ itọju

Therefore, the IPC standard is the industry standard for almost all steps of PCB design, from design, production to electronic assembly.

IPC standards fall into several categories. IPC-A-610 jẹ eyiti a lo julọ julọ. Awọn eroja kan ti o bo nipasẹ IPC-A-610 pẹlu, ṣugbọn ko ni opin si:

ooru rii

ta

Asopọ ebute

Fifi sori ẹrọ paati

Chip components

amination conditions

Some of the fundamentals of the IPC-A-610 class are:

ipele 1

Eyi kan si ẹrọ itanna idi gbogbogbo nibiti iṣẹ paati akọkọ ti nilo lati pari. Therefore, this is considered to be one of the most lenient categories in terms of allowing potential defects and is therefore not an OEM required category.

ipele 2

This is a standard often used for non-critical components, where long-term reliability is a prerequisite, although this class allows for a certain degree of defect.

ipele 3

This is the highest standard available for more critical PCB components. Nitorinaa, awọn olupese CEM ti o dara julọ yoo gbejade awọn ọja ti o pade awọn ipele 3 ipele. iwulo gidi wa fun awọn idiyele ti o ga julọ nitori ayewo afikun ti o nilo ati iwulo lati fa fifalẹ oke oke lati rii daju pe iṣedede oke ti o nilo.
