Ko etahi tohu noa hei tuhi i te wa e hoahoa ana koe Poari PCB:

I. He whakamaarama taipitopito mo nga taapiri hoahoa PCB e pa ana

1. The line

(1) Te whanui raina iti: 6mil (0.153mm). Ko te kii, mena ka iti ake te whanui raina i te 6mil, kaore e taea te whakaputa. Mena ka whakaae nga ahuatanga hoahoa, ka nui ake te hoahoa, ka pai ake te whanui raina, ka pai ake te hanga wheketere, ka teitei ake te hua. Ko te huihuinga hoahoa whanui kei te takiwa o te 10mil, he mea nui tenei waahanga, me whakaaro ki te hoahoa.

(2) Mokowhiti raina iti: 6mil (0.153mm). Ko te tawhiti o te raina iti, ara, raina ki te raina, raina ki te tawhiti papa kaore e iti iho i te 6mil mai i te tirohanga whakaputa, ko te rahi ake o te pai, ko te whanui i te 10mil, mo te tikanga, ko nga ahuatanga hoahoa, ko te nui ake ko te pai ake. wāhi he tino nui, me whakaaro i roto i te hoahoa.

(3) Te tawhiti mai i te raina ki te raina contour 0.508mm (20mil)

2. Ma te poka (e mohiotia ana ko te poka kawe)

(1) Iti iti rawa: 0.3mm (12mil)

(2) Ko te kohinga iti rawa ma te poka (VIA) ko te uruwhenua kia kaua e iti iho i te 0.3mm (12mil), te papa kotahi kia kaua e iti iho i te 6mil (0.153mm), ko te mea nui ake i te 8mil (0.2mm) kaore e iti (tirohia te Whakaahua 3 ) he mea nui tenei tohu, me whakaaro ki te hoahoa

(3) na roto i te poka (VIA) poka ki te mokowhiti poka (taha poka ki te poka taha) kaua e iti iho i te: 6mil pai ake i te 8mil he nui rawa tenei waahanga, me whakaaro ki te hoahoa

(4) Distance between pad and contour line 0.508mm(20mil)

(5) a. Hole to line spacing:

NPTH(without welding ring) : hole compensation 0.15mm back distance line more than 0.2mm

PTH (me te mowhiti whakakai): poka utu 0.15mm me runga ake i te raina tawhiti 0.3mm

B. Hole-to-hole spacing:

PTH (me te mowhiti paiherea): 0.15mm i muri i te utu o te koha ki te 0.45mm neke atu ranei

NPTH hole: 0.15mm to 0.2mm after hole compensation

VIA: The spacing can be slightly smaller

3. PAD PAD (commonly known as plug hole (PTH))

(1) Ko te rahinga o te kohao plug kei i to waahanga, engari me nui ake i to pine waahanga. E taunaki ana kia rahi ake te titi mono mai i te 0.2mm iti rawa, ara, 0.6 o te pine waahanga, me hoahoa e koe kia rite ki te 0.8 iti rawa, kia aukati i te manawanui o te miihini na te whakauru uaua i whakauru.

(2) Poka poka (PTH) mowhiti o waho taha unilateral kaua e iti iho i te 0.2mm (8mil), ko te tikanga, ko te rahi ake o te pai (e whakaaturia ana i te Whakaahua 2) he mea nui tenei tohu, me whai whakaaro te hoahoa.

(3) Poka poka (PTH) poka ki te mokowhiti poka (mata poka ki te poka poka) kaua e iti ake i te: 0.3mm o te akoranga, ko te rahi ake o te pai (kua tohua ki te ATA.3) He mea nui tenei tohu, me matua whakaarohia i roto i te hoahoa

(4) Distance between pad and contour line 0.508mm(20mil)

4. Te herenga

(1) Tuwhera matapihi poka-i te tuwhera matapihi, ko te taha whakatuwhera matapihi SMD kaua e iti iho i te 0.1mm (4mil)

5. Nga Pūāhua (ko te hoahoa o te kiripuaki e pa ana ki te hanga, me te maarama o nga kiripuaki e pa ana ki te hoahoatanga o nga kiripuaki)

(1) ko te whanui kupu ahua kaore e taea te iti iho i te 0.153mm (6mil), ko te kupu teitei kaore e iti iho i te 0.811mm (32mil), ko te whanui ki te teitei o te hononga pai ko te 5 ara, kupu whanui 0.2mm kupu teitei ko te 1mm, kia peehi ai te akomanga

6. The minimum spacing of non-metallic grooves should not be less than 1.6mm, otherwise it will greatly increase the difficulty of edge milling (Figure 4)

7. Tihi

(1) toirau me te kore he kohinga taapiri, me te kohinga mokowhiti, ko te waahi taapiri me te waahi kaore e iti iho i te 1.6 mm (te matotoru o te 1.6) mm, mena ka nui rawa atu te uaua o te mira o te raahi mahi pereti mahi, kaore i te. he rite ano ki nga taputapu rereke, ko te waahi kaore he waahi pakaru mo te waahanga tukatuka 0.5mm kaore e iti iho i te 5mm

Ii Nga take e tika ana kia tirohia

1. Tuhinga tuuturu mo te hoahoa PADS.

(1) Ko nga PADS e whakatakotoria ana ki te momo parahi, a ko ta maatau kamupene e tuu ana i te parahi i roto i te momo Hatch. Whai muri i te nekehanga o nga konae taketake o te kaihoko, me whakatakoto ano ki te parahi hei pupuri (parahi waipuke waipuke) kia kore ai e ara poto.

(2) Ko nga ahuatanga o te kanohi kei roto i te PADS-takirua kia tautuhia ki roto Na roto, kaua ki te ParTIal. Kaore e taea te hanga i nga konae pupuhi, ka hua ake te turuturu.

(3) Kaua e tapirihia nga riu hangaia ki te PADS me nga waahanga, na te mea kaore e taea te hanga i te GERBER. Kia kore ai e rere te mokamoka, tena koa tapiri he riu ki te DrillDrawing.

2. Tuhinga e pa ana ki te hoahoa PROTEL99SE me te DXP

(1) Our company’s Solder mask layer is subject to Solder mask layer. If the Paste layer needs to be made, and the Solder window with multiple layers cannot generate GERBER, please move to the Solder layer.

(2) Kaua e raka te raina horopaki i te Protel99SE. Kaore e taea te hanga GERBER i te tikanga.

(3) I roto i te konae DXP, kaua e kowhiria te waahanga KEEPOUT, ka tirotirohia te raina takiwa me etahi atu waahanga, kaore e taea te whakaputa GERBER.

(4) Tena koa kia aro mai ki te hoahoa pai me te kino o enei momo tuhinga e rua. I runga i te tikanga, he pai te paparanga o runga, a, ko te paparanga o raro kia hangaia hei whakamuri. Ka mahi pereti ta maatau kamupene ma te taatai ​​mai i runga ki raro. Takitahi te pereti takitahi, kaua e whakaata i taau e pai ai! Akene kei kona ke atu

3. Etahi atu whakatupatotanga.

(1) Ko te Hanga (penei i te papa pereti, mokamoka, V-tapahia) me tuu ki te papa KEEPOUT paparanga miihini ranei, kaore e taea te whakanoho ki etahi atu papa, penei i te papanga taarua mata, raina raina. All slots or holes that need mechanical molding should be placed in one layer as far as possible to avoid leakage.

(2) mena he koretake te papa miihini me te papa KEEPOUT e rua nga ahua o te ahua, tena koa hangahia nga tohutohu motuhake, haunga te ahua ki te hanga whaihua, penei i te riu o roto, me te riu whakawhiti a-roto o waho. ko te waahanga me whakakore, ko te riu kore-roto o te riu o roto, ko te hoahoa i te papa miihini me te riu papae KEEPOUT me te kohao e hangaia ana e te poka parahi (mahia te kiriata ki te keri parahi), If it needs to be processed into metal holes, please make special remarks.

(3) If you want to do the metalized slot the most safe way is to put together a plurality of pad, this approach must not go wrong

(4) Tena koa tuhia he tuhinga motuhake mena he mea tika te mahi tukatuka peera i te wa e tuu ana te ota mo te pereti maihao koura.

(5) Tena tirohia mena he iti ake nga papa o te konae GERBER. Ko te tikanga, ka whakaputahia e ta maatau kamupene kia rite ki te konae GERBER.

(6) Use three kinds of software design, please pay special attention to whether the key position needs to expose copper.
