Apparatus for spreading material onto a substrate

Apparatus for pushing a paste substance through the apertures of a workpiece and onto a circuit board, comprising:

• a housing having a groove extending therethrough and which is coequal in length with the housing;
• a pair of oppositely-disposed, arch-shaped locking clamps mountable to both ends of the housing, and each clamp having a pair of opposed legs for defining a channel through which the shaft is inserted;
• an elongated shaft having a longitudinal slot, the shaft disposed within the groove of the housing and channels of the clamps for selective rotation therein;
• and
• an elongated blade mounted within the slot and which rotates concomitant with the rotation of the shaft in order to selectively adjust the angle between the blade and the circuit board.

Apparatus for spreading a paste substance onto a circuit board, comprising:

• a housing having a groove extending therethrough and which is coequal in length with the housing;
• a pair of oppositely-disposed, arch-shaped locking clamps removably attachable to both ends of the housing and each clamp having a pair of opposed legs which define a channel;
• spreading means for spreading the paste substance onto the circuit board, the spreading means inserted into the groove of the housing and the channels of the locking clamps for selective rotational movement therein to vary the angle between the spreading means and the circuit board;
• and
• a means to tighten the legs of the clamps which is securable to the locking clamps for fixing the angle between the spreading means and the substrate.

Apparatus for spreading a paste substance on a circuit board, comprising:

• an elongated blade holder having a channel coequal in length therewith;
• an elongated shaft having a longitudinal slot coequal in length therewith, the shaft completely enclosed within the channel for selective rotatable movement therein;
• an elongated blade mounted to the shaft for rotation concomitant with the shaft rotation, the blade projecting downwardly at a predetermined angle to the circuit board when the shaft is disposed within the channel of the blade holder;
• and
• means to fix the angle of the blade relative to the circuit board which extends within the blade holder for compressing the blade holder against the shaft.

Apparatus for spreading a paste substance on a circuit board, comprising:

• an elongated blade holder having a channel coequal in length therewith;
• an elongated, tubular-shaped shaft for removable insertion within the channel of the blade holder and disposed for selective rotatable movement therein;
• the shaft having a longitudinal slot coequal in length with the shaft so that the shaft does not form a closed circle along the axial length of the shaft;
• an elongated blade formed from the shaft and projecting away from the shaft axis and toward the circuit board;
• the blade rotatable concomitant with the rotation of the shaft so that the angle between the blade and the circuit board can be adjusted;
• and
• means to fix the angle of the blade relative to the circuit board which extends through the blade holder for compressing the blade holder against the shaft.
