Momwe mungasankhire kumaliza koyenera kwa PCB yanu?

Nawa maupangiri akatswiri opangira chisankho ichi:

1. Kukwanitsa

Pankhani ya kufananiza pakati pa HASL yopanda kutsogolera ndi HASL yotsogolera, tinganene kuti zakale ndizokwera mtengo kwambiri.Chifukwa chake, ngati muli ndi bajeti yolimba kapena mukufuna kusunga ndalama, kupita kukamaliza kutsogolera kwa HASL ndi njira yabwinoko yosungira ndalama.

2. Kutsata kwa RoHS

Chifukwa cha zovuta zaumoyo ndi zovulaza zomwe zimagwirizanitsidwa ndi kugwiritsa ntchito zipangizo zamagetsi, kuya kwa kuwonekera komwe kuyang'ana gulu lozungulira kumabweretsa kwa wogwiritsa ntchito kuli kopindulitsa.

Kutsata kwa RoHS tsopano ndiye muyeso wama projekiti ambiri a PCB ndipo ogula ambiri akulabadira mbali iyi.Pazifukwa izi, kusankha zinthu zopanda lead za HASL ndi njira yabwinoko ngati mukufuna kupanga ma board oyendera a RoHS.

Izi zili choncho chifukwa cha kuchuluka kwa malata ndi mkuwa wochepa.Popeza palibe chitsogozo chomwe chikugwiritsidwa ntchito pano, mutha kukhala otsimikiza kuti zovuta zaumoyo zomwe zimadzetsa sizodetsa nkhawa.

Chofunikira pakupambana, komabe, ndikuti palibe zigawo zomveka bwino pa PCB.Zida monga ma BGA ndi ma SMD sizoyenera pankhaniyi.

3. Zofunikira zokhazikika

Kuphatikiza pa kuteteza mkuwa ndi zigawo zina zofunika, ntchito ya chithandizo chapamwamba iyenera kupititsa patsogolo kukhazikika kwa PCB.Bolo likamakhala lolimba kwambiri chifukwa chakugwiritsa ntchito kwake, limakhala lalitali.

4. Kugwiritsa ntchito ndi kugwira ntchito

Kugwiritsiridwa ntchito, mwachitsanzo, pamene bolodi yotsekedwa ndi zomalizazi zidzagwiritsidwa ntchito, ndizofunikira kwambiri.Pachifukwa ichi, kugwiritsa ntchito kapena kugwiritsa ntchito kuyenera kuganiziridwa kuti zithandize kusankha koyenera.

5. Ganizirani za chilengedwe

Osasokoneza chilengedwe ndi pulogalamu kapena ntchito.Ndi chilengedwe apa tikutanthauza mtundu kapena mulingo wa mawonekedwe omwe bolodi losindikizidwa (PCB) litha kuwonekera likakhala kuti litakutidwa ndi mapeto a pamwamba.

Chilengedwe nthawi zambiri chimatanthawuza mulingo wa kutentha - kaya ndi wovuta kapena wofatsa.Kuti mupeze zotsatira zabwino, gwiritsani ntchito zinthu zopanda lead za HASL chifukwa zimagwirizana ndi RoHS, zomwe zimapangitsa kuti zikhale zaubwenzi kwa ogwiritsa ntchito komanso malo ozungulira.

6. Sankhani ENIG pa HASL lead-free surface treatment

Zosankha zazikulu zitatu (3) zomwe musanachitike pakumaliza kwa PCB ndi HASL, HASL Lead Free ndi ENIG.Ngakhale zida zitatuzi zili ndi katundu wosiyana, chimodzi chingakhale chosankha chabwinoko kuposa china.

Choyamba, muyenera kusankha HASL yopanda kutsogola kuposa HASL chifukwa imagwirizana ndi RoHS, zomwe zikutanthauza kuti ndizotheka kuigwiritsa ntchito pazomaliza za PCB zingapo.Mfundo yakuti imapereka solderability yabwino kwambiri ndi malo ena ogulitsa.

Kumbali ina, ngati mukufuna kusunga ndalama ndikugwira ntchito pa PCB zomwe zimafuna kutentha pang'ono, ndiye kuti HASL ndi chisankho chabwino.

Ngati simukutsimikiza ngati onse a HASL osatsogolera komanso HASL agwira ntchitoyo, ndiye kusankha golide wopanda nickel (ENIG) ndiye njira yabwino kwambiri.Kuphatikiza apo, ENIG ili ndi mawonekedwe ofanana ndi HASL yopanda lead, monga kutsata RoHS.

ND2+N8+AOI+IN12C

Zhejiang NeoDen Technology Co., Ltd. yakhala ikupanga ndi kutumiza kunja makina osiyanasiyana ang'onoang'ono osankha ndi malo kuyambira 2010. Kutengera mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, NeoDen imapeza mbiri yabwino kuchokera kwa makasitomala padziko lonse lapansi.

Timakhulupirira kuti anthu abwino ndi othandizana nawo amapangitsa NeoDen kukhala kampani yabwino komanso kuti kudzipereka kwathu ku Innovation, Diversity and Sustainability kumawonetsetsa kuti makina a SMT azitha kupezeka kwa aliyense wokonda zosangalatsa kulikonse.
