プッシャー方式
装置原理
この装置は、従来のプッシャー方式ですが、特にＰＷＢ電気めっき用途に当社が開発しためっき部の構造及びＰＷＢ又は冶具間の隙間
を最小限に制御し、連続搬送を行う事を特徴とした搬送装置です。
性能面の特徴（主にキャリアー方式と比較）
４．薄板対応
１．銅めっき槽内連続搬送
常に全数のアノード間をＰＷＢが移動し、めっき処理が行われ
る為、全てのＰＷＢの膜厚が均一です。
２．めっき槽が１つであり、めっき液の管理（濃度、温度等）
が容易です。
３．ＰＷＢ表裏のめっきバラツキが少ない。
槽内のガイド機構によりアノードとＰＷＢの平行度が保たれる
為、
ＰＷＢ表裏のバラツキが少なくなります。
ＰＷＢの上部を直接クランプし、
０.１ｍｍ迄の薄板搬送が可能
(入槽ガイド、槽内液中ガイドによる対応)
５．カソード及びアノード遮蔽
ＰＷＢの高さ方向のめっき膜厚コントロールは自動で下端遮
蔽板を制御します。上端は固定遮蔽板
６．ＰＷＢ寸法の変更が容易
ＰＷＢ寸法(進行方向)に合わせて上部クランパー部を自動
調整します。
環境対策
めっき槽内は液中を基板が移動する為、上部開口面をカバーする事により、排気量の削減が可能です。又、排気吸引口をめっき槽の上
部に設置することで、下から立上がるミストを確実に補足することが可能です。この事により作業環境の向上及び装置の腐食を抑える
ことが出来ます。
アノードボールの補給
作業面及び反作業面の距離が短い為、アノードボールの補給は容易に行えます。
装置の操作及び故障率
構造が単純である為、操作は簡単であり、故障の発生率が少ない。
処理液中への異物の落下防止
通常プッシャー方式の場合、摺動レールが槽の上部に配置されますが、本機の場合、摺動レールを槽の側面に配置しているので、液
中への異物の落下がなく精密部品にも対応できます。
装置へのＰＷＢの着脱方法
冶具の構造により自動化、手作業の選択となります。
上部クランプ方式の場合はロード部においてＰＷＢを水平から垂直に面転を行いクランパーに取付けます。
クランパーからのアンロードはＰＷＢをクランパーより開放し、垂直から水平姿勢に面転を行います。
ウエムラは薬品メーカーとしてのノウハウを反映させた、キャリア、エレベータタイプや水平搬送装置(Ｃｃｏｎ)、

Vertical Continuous Copper Plating System for PWBs
Principles
●
Configuration Pretreatment section
pusher system
Plating section
During copper plating, the clearances between printed circuit boards (PWBs) are kept to a minimum while PWBs are conveyed continuously.
Post-treatment section
pusher system
● Working
Principles
Ucon-Jr adopts a conventional pusher system, but has a construction developed by Uyemura particularly for the PWB copper
electroplating application. It is a conveyor system designed to continuously convey PWBs while controlling clearances between
PWBs or plating jigs to a minimum.
Features of Performance (primarily compared with a carrier system)
1. Continuous conveyance during copper plating
Since PWBs constantly travel between all the anodes as
electroplating takes place, uniform plating thickness is
achieved for all PWBs.
2. There is only one plating tank used, making it easy to control
the plating solution (concentration, temperature, etc.).
3. Less plating thickness variations between the front-side and
the rear-side of PWBs
Because parallelism is maintained between the anode and
PWB by the guide mechanism in the plating tank, thickness
variations between the front-side and rear-side of PWBs are
reduced.
4. Thin panels
The top of the PWB is directly clamped and thin panels of
up to 0.1 mm can be conveyed.
(Thin panels are received and guided by the entry guide
and in-bath guide inside the plating tank).
5. Cathode and anode screens
The plating thickness uniformity in the PWB height
direction is controlled by automatically controlling the
bottom end screen with the top end screen fixed.
6. Easy change of PWB size
The upper clamper section can be automatically adjusted
to satisfy any PWB size (transfer direction).
Environmental Measures
Because PWBs travel inside the plating tank, covering the top opening surface can reduce emission. In addition, by locating the
exhaust and intake ports at the top of the plating tank, chemical mist can be absorbed efficiently. These features will certainly
improve working environments and can suppress corrosion of the plating equipment.
Replenishment of Anode Balls
Because the distance between the working side and counter working side is close, anode balls can be easily replenished.
Operation and Failure Rate
The simple construction design of Ucon-Jr achieves easy operation and reduces the failure occurrence rate.
Prevention of Foreign Object Contamination into Treatment Solutions
In a general pusher system, transfer rails are located above the process tanks. In the case of Ucon-Jr, transfer rails are located
on the side of the process tank, which prevents foreign objects from falling in the process solution, and allows precision parts to
be plated efficiently.
How to Load and Unload PWBs
Automatic or manual operation will be chosen according to the design of the plating jigs.
In the case of a top clamp system, the PWBs are inverted from horizontal position to vertical position at the loading section and
are mounted to the clamper. PWBs are unloaded by releasing the PWB from the clamper and are inverted from the vertical
position to the horizontal position.
Uyemura designs and builds plating equipment with various kinds of conveyors including carriers, elevator types, horizontal
conveyors (Ccon), vertical conveyors (Ucon), etc. with its know-how as a plating chemical manufacturer generously fed back
to its plating machinery products. Uyemura consistently satisfies any customers’ unique and diverse requirements.
