Dab tsi yog metallized castellated qhov PCB

Nrog rau txoj kev loj hlob sai ntawm cov khoom siv hluav taws xob, miniaturization ntawm high-density thiab multi-function tau dhau los ua txoj kev loj hlob. Cheebtsam ntawm cov ntawv luam tawm Circuit Board tau nce geometrically thaum lub rooj tsavxwm loj zuj zus tuaj, feem ntau xav tau cov rooj tsav xwm me me.

Dab tsi yog metallized castellated qhovPCB

Lub ntsiab txhais ntawm metallized castellated qhov yog tias thawj lub qhov yog drilled thiab tom qab ntawd drilled, thiab cov txheej txheem zoo tiav. Thaum kawg, ib nrab ntawm lub qhov metallized (groove) yog tshwj tseg. Cias muab, ib nrab ntawm lub qhov metallized ntawm ntug ntawm lub rooj tsavxwm raug txiav. Hauv kev lag luam PCB, nws tseem hu ua lub qhov nyiaj stamping. Nws tuaj yeem txuas ncaj qha rau ntawm ntug ntawm lub qhov mus rau lub ntsiab ntug, uas tuaj yeem txuag cov khoom sib txuas thiab qhov chaw. Nws feem ntau tshwm nyob rau hauv cov teeb liab circuits.

Yog hais tias lub voj voog ntawm lub rooj tsav xwm me me yog soldered rau lub rooj tsav xwm hauv niam lub rooj tsav xwm nrog cov solder, vim qhov loj ntawm lub voj voog lub qhov, muaj teeb meem ntawm cov khoom siv hluav taws xob, uas ua rau tus me nyuam thiab leej niam luam tawm Circuit Court boards tsis tuaj yeem ua hluav taws xob. txuas zoo, yog li lub rooj tsav xwm metallized semi-conductive tshwm. Orifice PCB. Metallized ib nrab-qhov board PCB nta: tus neeg yog me me, thiab muaj tag nrho cov kab ntawm metallized ib nrab-qhov nyob rau sab ntawm chav tsev. soldered ua ke.

Castellated qhov PCB txheej txheem

1. txheej txheem ib nrab-sab qhov nrog ob V-zoo li tus txiav cuab yeej.

2. Lub laum thib ob ntxiv cov lus qhia ntawm lub qhov ntawm sab ntawm lub qhov, tshem tawm cov tawv nqaij ua ntej, txo cov burrs, thiab siv cov groove cutters es tsis txhob xyaum ua kom zoo dua qhov ceev thiab poob ceev.

3. Muab tooj liab rau electroplate lub substrate, yog li ntawd ib txheej ntawm tooj liab yog electroplated rau ntawm lub qhov phab ntsa ntawm lub puag ncig lub qhov ntawm ntug ntawm lub rooj tsavxwm.

4. Kev tsim cov txheej txheej txheej tom qab lamination, raug, thiab kev loj hlob ntawm cov substrate nyob rau hauv ib theem zuj zus, lub substrate yog raug mus rau theem nrab tooj liab plating thiab tin plating, thiaj li hais tias cov tooj liab txheej nyob rau hauv lub qhov phab ntsa ntawm lub puag ncig lub qhov ntawm ntug ntawm lub rooj tsavxwm yog thickened thiab tooj liab txheej yog them nrog ib tug tin txheej rau corrosion kuj;

5. Ib nrab-qhov sib sau Txiav lub qhov puag ncig ntawm ntug ntawm lub rooj tsavxwm hauv ib nrab los ua ib nrab-qhov;

6. Nyob rau hauv cov kauj ruam ntawm kev tshem tawm cov yeeb yaj kiab, cov yeeb yaj kiab los tiv thaiv electroplating nias thaum lub sij hawm nias cov txheej txheem yog tshem tawm;

7. Etching Lub substrate yog etched, thiab cov tooj liab raug rau ntawm txheej txheej ntawm substrate raug tshem tawm los ntawm etching;

8. Tin stripping Lub substrate yog stripped ntawm tin, thiaj li hais tias cov tin nyob rau hauv ib nrab-qhov phab ntsa yuav raug tshem tawm, thiab cov tooj liab txheej nyob rau hauv ib nrab-qhov phab ntsa yog nthuav.

9.Tom qab tsim, siv daim kab xev liab los lo rau lub rooj sib tham ua ke, thiab tshem tawm cov burrs los ntawm kab alkaline etching.

10. Tom qab ob txheej tooj liab plating thiab tin plating ntawm lub substrate, lub puag ncig lub qhov ntawm ntug ntawm lub rooj tsavxwm yog txiav nyob rau hauv ib nrab los tsim ib tug Castellated qhov, vim hais tias cov tooj liab txheej ntawm lub qhov phab ntsa yog them nrog ib tug tin txheej, thiab cov tooj liab. txheej ntawm lub qhov phab ntsa yog kiag li zoo nrog cov tooj liab nyob rau hauv txheej txheej ntawm lub substrate Connection, uas muaj zog bonding quab yuam, muaj peev xwm tiv thaiv tau cov tooj liab txheej ntawm lub qhov phab ntsa los ntawm raug rub tawm los yog tooj liab warping thaum txiav;

11. Tom qab lub qhov castellated tsim, cov yeeb yaj kiab raug tshem tawm thiab tom qab ntawd etched, kom cov tooj liab saum npoo yuav tsis raug oxidized, kom tsis txhob muaj qhov tshwm sim ntawm cov seem tooj liab los yog luv luv Circuit Court, thiab txhim kho cov txiaj ntsig ntawm cov hlau ib nrab ntawm lub qhov. PCB Circuit Board.

Qhov nyuaj hauv metallized Castellated qhov PCB ua:

1. Metallized Castellated qhov PCB tau blackened tooj liab daim tawv nqaij ntawm lub qhov phab ntsa, burrs, thiab misalignment tom qab sib sau, uas yeej ib txwm yog ib qho teeb meem nyuaj nyob rau hauv lub txheej txheem ntawm ntau yam PCB factories.

2. Tshwj xeeb tshaj yog tag nrho cov kab ntawm ib nrab-qhov uas zoo li cov ntawv xa ntawv lub qhov, lub qhov taub yog li 0.6mm, lub qhov phab ntsa qhov sib nrug yog 0.45mm, thiab cov qauv sab nraud yog 2 hli. . Vim tias qhov sib txawv me me, nws yooj yim heev los ua kom luv luv vim yog cov tawv nqaij tooj liab.

3. Cov txheej txheem metallized ib nrab-qhov board PCB molding txheej txheem muaj xws li CNC milling tshuab gong board, mechanical punch punching, VCUT txiav thiab lwm txoj kev. Thaum cov txheej txheem no tshem tawm qhov tsis tseem ceeb ntawm lub qhov tooj liab, nws yuav ua rau cov xov tooj tooj liab thiab cov burrs tseem nyob rau ntawm qhov seem ntawm PTH qhov seem, thiab nyob rau hauv cov xwm txheej hnyav, cov tawv tooj liab ntawm tag nrho lub qhov phab ntsa yog lifted thiab tev. tawm.

Ntawm qhov tod tes, thaum lub qhov metallized castellated yog tsim, vim muaj kev cuam tshuam ntawm PCB expansion thiab contraction, drilling qhov qhov raug, thiab tsim raug, sab laug thiab sab xis ntawm tib chav tsev muaj qhov sib txawv loj ntawm qhov seem ntawm qhov seem. castellated qhov thaum lub sij hawm txheej txheem. Tuaj ntsib teeb meem loj.
