IPC Kirasi Mitemo yePCBs
IPC Overview
IPC iboka rinogadzira mitemo yemagetsi. Vanobatsira makambani kugadzira, kuvaka, uye kutarisa mabhodhi edunhu akadhindwa. Mitemo yeIPC inovhara nhanho yega yega, sekunhonga zvinhu uye kutarisa chigadzirwa chekupedzisira. Iyi mitemo inobatsira vanogadzira kuchengetedza basa ravo rakafanana uye kugadzira zvigadzirwa zvakanaka. IPC kirasi zviyero zvePCBs ipa mitemo yakajeka yekugadzira, nzvimbo, uye kutonga kwekupisa. Vanobatsirawo nekunhonga zvinhu uye kuyedza mabhodhi. Kana makambani achitevera mitemo yeIPC, anoita zvikanganiso zvishoma uye mabhodhi avo anogara kwenguva refu.
Mitemo yeIPC inobatsira makambani kutevera mitemo yakafanana kwese kwese. Makambani mazhinji emagetsi anoda kuti vatengesi vavo vashandise mitemo iyi. Izvi zvinoita kuti maPCB ave emhando yakanaka kunyangwe akagadzirwa kupi. IPC mitemo inobatsirawo kuyedza zvinhu nekutarisa mabatiro avanoita kupisa uye kusagadzikana. Iyi bvunzo inotarisa tembiricha yekushanduka kwegirazi (Tg), tembiricha yekuora (Td), uye coefficient yekuwedzera kwekushisa (CTE).
Basa muPCB Hunhu
IPC kirasi zviyero zvePCBs zvinobatsira kuve nechokwadi kuti mabhodhi akanaka uye anogara kwenguva refu. Mitemo iyi inotaura izvo zvakanaka kune yega yega yePCB, kubva kune akareruka gadget kuenda kune yakakosha nzvimbo michina. IPC mitemo kufanana neIPC-J-STD-001 vane matanho akasimba ekutengesa, kuisa zvikamu pamwe chete, uye kutarisa mabhodhi. Vanoudza makambani kuti ashandise maturusi akakodzera, kuchengeta nzvimbo yebasa yakachena, uye kudzidzisa vashandi zvakanaka. IPC-A-610 inopa mifananidzo yakajeka kubatsira vanhu kutarisa kana mabhodhi akatarisa zvakanaka.
