Patent ID: 7943018

Claim:
An electroplating apparatus for treating flat, brittle substrates, the apparatus comprising: a treatment chamber, in which the substrates can be acted upon by a treatment liquid; a transport device, by means of which the substrates can be guided so as to pass horizontally through the treatment chamber; at least one lateral guide device which acts on outer edges of the substrates, wherein the outer edges of the substrate are oriented substantially parallel to the conveying direction; and, at least one counterholding device which acts on upward pointing sides of the substrates to prevent the latter from lifting off the transport device, wherein the at least one counterholding devices comprises mating rollers which serve as contact devices for electrically contacting the substrates to be treated, wherein the mating rollers are mounted on a flexible shaft being capable of deflecting even under small forces; wherein the lateral guide device comprises cylindrical, rotatably mounted lateral guide rollers.
