Kugwiritsa ntchito makulidwe oyenera azinthu ndikofunikira yomanga FR4 PCBS. Makulidwe amayeza mainchesi, monga masauzande, mainchesi, kapena mamilimita. Pali zinthu zingapo zofunika kuziganizira mukamasankha cholemba cha FR4 cha PCB yanu. Malangizo otsatirawa atero  pangani chisankho chanu:

Double-Sided-PCB (3)

1. Sankhani zipangizo zopyapyala za FR4 zomanga mapanelo okhala ndi zopinga zapompano. Zipangizo zopapatiza zimatha kuthandizira zinthu zosiyanasiyana zopanga zida, monga zida za Bluetooth, zolumikizira za USB, ndi zina zotero.

 

2. zida zopyapyala za FR4 ndizoyenera ntchito zomwe zimafunikira kusinthasintha. Mwachitsanzo, kugwiritsa ntchito zida zochepa za PCB zamagalimoto ndi zamankhwala ndikofunikira chifukwa ma PCB awa

amafunika kupindidwa pafupipafupi.

Pewani kusankha zida zazing'ono zopangira ma PCB, chifukwa izi zimawonjezera chiopsezo chowonongeka kapena kuphulika kwa board.

 

3. Makulidwe azinthuzo angakhudze kulemera kwa bolodi losindikizidwa ndipo amathanso kukhudza kuyanjana kwa zinthu. Izi zikutanthauza kuti zinthu zopyapyala za FR4 ndizoyenera kuti zithandizire pakupanga ma board oyenda opepuka, omwe amadzetsa magetsi ochepa. Zinthu zopepuka izi ndizokongola komanso ndizosavuta kunyamula.

Nthawi yopewa kugwiritsa ntchito zakuthupi za FR4, zakuthupi za FR4 sizosankha bwino ngati pulogalamu yanu ikufuna izi: Kutentha kwambiri: FR4 siyikulimbikitsidwa ngati PCB ingagwiritsidwe ntchito m'malo otentha. Mwachitsanzo, zakuthupi za FR4 sizoyenera kusankha kwa PCB mukamagwiritsa ntchito ndege.

Kuwotcherera kopanda lead: Ngati kasitomala wanu akufuna A PCB kutsatira RoHS, kuwotcherera kopanda lead kuyenera kugwiritsidwa ntchito. Pakati pa soldering yopanda kutsogolera, kutentha kwa Reflux kumatha kufika pachimake pa 250 ° C, ndipo chifukwa cha kutentha kwake kotsika, zinthu za FR4

sangapirire nazo.

Chizindikiro chapafupipafupi: Mukawululidwa ndi chizindikiritso chapamwamba, mbale ya FR4 imatha kukhalabe ndi mpweya wabwino. Zotsatira zake, kusinthasintha kumachitika ndipo kumatha kukhudza kukhulupirika kwa chizindikirocho.

 

Chifukwa kutchuka kwawo ndi ntchito lonse, lero n'zosavuta kupeza zipangizo FR4 PCB pamsika ndi zosiyanasiyana za specifications ndi ntchito. Zosankha zabwino zotere nthawi zina zimapangitsa zisankho kukhala zovuta. Poterepa, ndikofunikira kukambirana zomwe mukufuna ndi wopanga.
