P版.comを利用したことは何度かあって、試作のための小さな基板が2.5万円ぐらいかかる(PCB製造のみで)のが相場です.これが、海外メーカーだと半額かそれ以下で出来そうだというのがトライしてみる動機です.品質は悪いらしいんですけどね.たった1万円で作れるなら気軽に試作できます.
●PCBCARTという中国のメーカーです.http://www.pcbcart.com/cart.php
製造できるPCB諸元はこうなっているようです.とくに問題ないと思います.
Layers 1-10 layers →両面基板
Material FR4 →FR4
Copper Thickness 1/2 to 2oz (18um-70um) →35um
Board Thickness .016-.126" (0.4mm-3.2mm) →1.6mm
Surface finish HASL,Ni/Au,OSP →フツー仕様
Soldermask LPI, different colors →フツー仕様
Board Dimension 600x700mm →93x48mm
Min Hole Diameter 8mil (0.2mm) →0.2mm
Min line width 8mil (0.2mm) →0.2mm
Min line spacing 8mil (0.2mm) →0.2mm
Min SMT pitch 16mil (0.4mm) →なんだろ? SMDの間隔?
Min. Annular Ring .008" (0.2mm) →via直径
Aspect Ratio 5:1 →なんだろ?
●作りたいPCBのAWはこんなです.
●onlineで基板諸元を入力して得た見積もりはこうです.credit/paypalでチャクっと決算します.
PCB $55 / 10pcs
Tooling cost $53
Shipping $20
Total $128 =おお~っ送料込みで約1万円!
●見積もり条件の抜粋はこうです.意味がわからない項目もあります.
Reorder Status なし
Quantity 10 pcs
Surface Finish HASL -Hot Air Solder Leveling
Copper Weight (Finished) 35 um
Min. Tracing/Spacing 0.20 mm 最もゆるい仕様
Min. Annular Ring 0.30 mm 最もゆるい仕様
Smallest Holes 0.40 mm 最もゆるい仕様
Holes Numbers Under 300 eagleから出力したドリルデータによると穴数は106個でした
Surface Mount 1 side
Soldermask Both Sides
Soldermask Color Green
Silkscreen Legend 1 side
Silkscreen Legend Color White
Gold Fingers No
Slots in Board No Slot in Board
Testing Yes
UL Marking No
Date Code Marking No
Lead Time in 12 days 長いけど安い方で
●データ受け渡しはどうしたらいいんでしょうか?
PCBCARTの説明によると、eagleの.brdファイルをそのまま受け入れてくれるようです.そりゃ簡単でいいわ.
もちろん他のCADであってもgerber fileで出力すれば受け入れてくれます.eagleでgerber file出力するには、P版.comが提供しているscriptを流用するとできます. http://www.p-ban.com/gerber/index.html
今回のデータ提出は、律儀にgerberですることにしました..brdだとシルクがどのレイヤで製造されるかがいまいちよくわからないので不安だからです.
↓これが送信するファイルの一覧表です.たぶんこれだけあれば受け入れてくれると思う.
RQ-STM8S-01.cmp Gerber layers Top (RS-274X format)
RQ-STM8S-01.gpi Report file
RQ-STM8S-01.plc Silkscreen Top
RQ-STM8S-01.sol Gerber layers Bottom
RQ-STM8S-01.stc Soldermask Top
RQ-STM8S-01.sts Soldermask Bottom
RQ-STM8S-01.out Outline data
RQ-STM8S-01.dri Drill Tool list
RQ-STM8S-01.drd NC Excellon Drill file
●ファイルの送信
注文画面にuploadボタンがありまして、そこからファイルを送信できます.ただしアタッチできるファイルは1つだけのようですので、zip圧縮してアタッチしました.これでいいのかな?
●INVOICE
ファイルを送信が完了するといきなり、INVOICE画面が表示されます.大事な書類だから印刷しておきました.
●データ受け取り連絡
今は夜だからかもしれませんが、決算メールは来ましたが、他にはデータ受け取りましたメールなどは来ませんです.わりと無愛想でしょうか?
さ~て、これでどうなるかな? 続報はこのページに追記してゆきます.
8月1日続報 : なーんも連絡ありません.つつがなく製作中なんだろうか? pcbcartサイトにloginしてorder statusを見るとprocessedになっています.processedっていうのは処理されたってことなんだろうか? delivery dateはnot availableのままなんです.
8月3日続報 : 質問メールが来ました. 1)3種混合基板だと追加料金です.2)中央付近のバカ穴の処置はどうする? という2点の質問です. 3種混合といえばそう言えなくもないけど、Vカット仕様でもないので 「1種です」と返答.次回からは複数混合と紛らわしいAWは避けようと思いました.バカ穴は「何も処置しなくていい」と返答. その後にメールが来て「ラジャー、PCBを作ります」とのことでした.ドリルとかビアにはデザインルール上の問題はなかったっぽいです.注文履歴のdelivery dateはまだupdateされてません. ともあれ本当に送料込みで1万円でPCBを製作できるようです.スゲー.
8月5日続報 : order historyによると出荷日8月14日とupdateされました
8月14日続報 : 8/14に出荷したとupdateされました
8月15日続報 : なんと、もう到着しました!驚き レポートはこちら

すごい時代になったもんですね~。
返信削除このくらいの規模でも、何か基板を起こすと50万くらい
掛かっていたような・・。
1万円なら、人件費を考えると手配線するより全然安い。
結果が楽しみです。
そうですね、会社の金でつくると50万円です.AW20万円.版下20万円.基板5万円.管理費5万円.そんな感じですかね.1万円なら失敗しても何度も作り直す気になります.
