発が望まれていた。In the manufacturing process of a ceramic circuit board, a circuit pattern is printed on a green sheet with a metal paste, and the circuit pattern is heated to solidify and fix the circuit pattern on the board.
If extra metal paste adheres to the printed circuit pattern for some reason and causes a swelling portion, it may contact another pattern. Therefore, before heating, the pattern is checked in a post-printing step, and excess metal paste is scraped off from the abnormally enlarged portion to complete the pattern. Therefore, it has been desired to develop an efficient method for correcting a print pattern.

パターン２は何らかの理由で余分な金属ペーストが付着
した箇所がある。In FIG. 3, a conductor pattern 2 made of a metal paste or the like is printed on the green sheet 1, and in this state, the pattern 2 is soft and not yet solidified. In this pattern 2, there is a portion where extra metal paste is attached for some reason.

察しながら、針状の工具を使用して余分な肥大部を削り
取って修正していた。If such an enlarged portion 3 is found by a microscopic inspection after printing, the operator corrects it. Conventionally, while observing with a stereoscopic microscope, a needle-shaped tool was used to scrape off and correct an excessively enlarged portion.

った。However, with the conventional correction method, it is difficult to accurately cut off the enlarged portion, and there is a drawback that it takes too much time, or it takes time to repeatedly cut due to insufficient cutting. Further, since the correction is made while looking at the stereoscopic microscope, the operator is burdened with the work, and there is a drawback that the work requires skill.
本発明は以上の問題点を解消するためになされたもの
で、異常な肥大部の金属ペーストを正確に削除して欠陥
パターンを容易に修正することを目的としている。The present invention has been made to solve the above problems, and it is an object of the present invention to accurately correct the defective pattern by accurately deleting the metal paste in the abnormally enlarged portion.

金属ペーストと前記研削剤とを吸引する様にした印刷パ
ターンの修正方法により達成できる。The above problem is to inspect a pattern printed with a metal paste on a green sheet, and if an abnormal enlarged portion is found on the pattern, the enlarged portion is reduced in a method of correcting the printed pattern, in which the enlarged portion is sandwiched. A step of arranging a spraying nozzle and a suction duct to face each other, and spraying air containing a powdered abrasive from the nozzle to the enlarged portion and scattering while keeping the duct at a negative pressure. This can be achieved by a method of correcting a print pattern in which the abrasive and the abrasive are sucked.

が可能となる。That is, according to the present invention, a pair of nozzles and ducts are arranged so as to face each other in the enlarged portion recorded at the time of inspection, and fine abrasive particles are blown together with air from the nozzles to the enlarged portion at high pressure. As a result, the excess metal paste in the enlarged portion is scattered, but the negative pressure suction duct absorbs these and eliminates the influence on the surroundings. The defective pattern can be repaired by a method that does not contact the pattern 2.
以下、本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第３図において、グリーンシート１上のパターン２に

リーンシート１を所定のステージに載置して顕微鏡で自
動装置又は人手により検査する。In FIG. 3, it is assumed that the pattern 2 on the green sheet 1 has a thickened portion 3 protruding laterally, and the thickened portion 3 is a portion to which a metal paste of an extra conductor is attached. For example, if the width of the pattern 2 is 80 to 100 μ, the enlarged portion 3 having a diameter of about 80 μ is caused by the protrusion of the metal paste during printing.
Occurs. In the manufacturing process of the ceramic circuit board, there is an inspection process at each stage, and the green sheet 1 after such pattern printing is placed on a predetermined stage and inspected by a microscope with an automatic device or manually.
次いで、パターン２上に肥大部３が発見された場合

て検査して、他にも肥大部３があり得るから、その後に
まとめて修正するためである。Next, when the enlarged portion 3 is found on the pattern 2, the scale of the stage is read and the position of the enlarged portion 3 is recorded. This is because the entire area of the green sheet 1 is inspected, and there may be other enlarged portions 3, so that they are collectively corrected.

せする。Next, the nozzle 4 having a diameter slightly smaller than the width of the pattern 2 and the suction duct 5 are moved toward the enlarged portion 3. The nozzle 4 blows out high-pressure air containing an abrasive having a predetermined hardness, and the duct 5 moving in opposition is kept at a negative pressure. The abrasive may be, for example, a fine powder of the same quality as the substrate being manufactured. After the coordinates of the enlarged portion 3 are read on the stage and positioned again within the field of view of the microscope, the pair of nozzles 4 and the duct 5 are moved to be arranged at positions facing each other across the enlarged portion 4. In the case of an automatic machine, the enlarged portion 3 is moved by the stage movement between the nozzle 4 and the duct 5, which are installed at the reference position in advance, to perform alignment.

により、非接触で欠陥パターンは修復される。Next, the powder of the abrasive is sprayed from the nozzle 4 at high speed together with the air and sprayed on the enlarged portion 3. Therefore, the enlarged portion 3 is removed by the air and the abrasive, and the excess metal paste and the abrasive powder and the air blown off are sucked into the duct 5.
As a result, the defect pattern is repaired in a non-contact manner by spraying an appropriate amount of air and powder of the abrasive.

度向上に寄与する。As apparent from the above invention, according to the present invention, when the position of the enlarged defect portion is recognized by the inspection, the enlarged portion is removed by blowing the abrasive such as alumina powder and air from the nozzle to remove the secondary obstacle. The defect pattern can be easily repaired without causing any damage. This contributes to improvement of the correction technique and reliability.
