Description
The compound half tone of a kind of metal forming and silk screen.
The present invention is with two kinds of compound half tones that material forms of copper metal forming and screen of fabric (nylon, wash human relations).The half tone that the present invention makes is used for the printing of the solder(ing) paste of surface mounting technology.The invention belongs to printed circuit board manufacturing technology field.
Always, in press, dyeing industry and printed circuit board manufacturing industry, the making of printing screen plate is with single screen of fabric (nylon, wash human relations) or woven wire, makes half tone by the figure transfer of photosensitive coating film.It has two kinds of manufacture methods usually: a kind of is " indirect method " system half tone, and the net that stretches tight is earlier made figure to the sensitization film by photographic process exposure, development again, this film with figure is attached to silk screen gets on.The half tone that this method is made, because the contraction or the amplification of size can take place when figure transfer the film, when being attached to the film on the silk screen, the contraction or the amplification of silk screen generation size cause the graph position precision of half tone low; Another kind is " direct method ", the net that stretches tight earlier, yet on silk screen the blade coating emulsion, expose again, develop and make half tone.This half tone is because when stretching tight net, the mesh of silk screen always has distortion in various degree, so the graphics shape on the half tone has sawtooth in various degree, the dimension of picture precision is low.
Above-mentioned two kinds of methods, also have following shortcoming: silk screen is to be made into and the tool mesh by silk thread, the seal material is bitten by mesh on the printed material.When mesh was big, biting property of seal material was good, but anti-seal is poor, and pattern precision is poor; When mesh hour, the pattern precision on the half tone correspondingly improves, but the biting property of seal material is poor; The half tone ubiquity of single silk screen irregular mesh distortion, dimension of picture precision and the figure relative position precision on the reduction half tone of causing of tension force.
The solder(ing) paste of surface mounting technology is sticking and thick, and the thickness of coat is thicker, about 0.15mm to 0.18mm, figure relative position precision height, therefore, the net glue of single silk screen can not satisfy its coating layer thickness and require and the requirement of figure relative positional accuracy, and the while solder(ing) paste can't be bitten on the printed material.So the half tone of single silk screen is not suitable for the usefulness of surface mounting technology printed solder paste.
The objective of the invention is to use a kind of economy, practical manufacture method makes being applicable to the half tone that prints with solder(ing) paste in the surface mounting technology.
The present invention can reach by following measure:
The compound half tone of this metal forming and silk screen, by metal forming 1, aluminium alloy cabinet 2 and silk screen 3 are formed, and it is characterized in that metal forming has the via hole image of certain precision, and are coated with thickening bright copper and bright nickel, are fixed by 107 glue and screen of fabric.When electroplating, minus plate is parallel to the swing of aperture direction.Through exposure, development, etched figure and electroplate the bright nickel of bright copper and form, the figure nominal dimension specified accuracy of its egative film is metal forming by photographic negative+0.02mm is to+0.05mm.
Accompanying drawing of the present invention is as follows:
Fig. 1: metal forming and silk screen composite web plate structure figure.
Fig. 2: process chart.
In Fig. 1,1 is the metal forming figure, and 2 is aluminium alloy net cabinet, and 3 is screen of fabric.
In conjunction with the accompanying drawings, the present invention realizes like this.The present invention adopts metal forming 1 to be the figure negative, and the seal material is imprinted on the printed material by the via hole image on the metal forming 1.Carrier is a screen of fabric 3, by the net tensioning of stretching tight half tone is obtained greater than 1.4N/cm
2Elastic force.According to mechanics beaer principle, metal forming with via hole image is considered as a stressed rigidity monomer, what produce when being subjected to around the screen of fabric of carrier stretching tight net tightens tension force and is passed to metal forming, forms two pairs of equal and opposite in directions, opposite the making a concerted effort of direction on metal forming.Therefore established figure on metal forming can be because of the net external force effect of stretching tight produce torsional deformation, thereby has overcome the shortcoming of traditional half tone mesh distortion.
The half tone that the present invention is made, thicken by electroplating bright copper and bright nickel on the figure metal forming owing to adopt, so can arbitrarily obtain different paper tinsel layer thicknesses, satisfy the requirement of the different-thickness of seal material coat, its bright copper coating is thick to be 0.05～0.12mm, and bright nickel layer thickness is 0.03～0.05mm.
The made half tone of the present invention has that anti-seal is good, and biting property is good, and dimension of picture is accurate, the advantage that graph position is correct.
Embodiment of the invention GE.46200.0036.52SI web plate has 1568 via hole images, and overall size is 230 * 108mm, and the aperture is Φ 0.6mm.
In conjunction with Fig. 2, manufacture method is described below.Operation 4, photographic negative is made.Take a picture with CAD or drafting photograph draft, or directly duplicate, but the present invention must determine a dimensional accuracy: A to the dimension of picture of photographic negative with former photograph egative film
+ 0.005 + 0.02Mm, A is the figure nominal dimension here.Operation 5, the metal forming clean adopts mechanical scratch brushing or the manual polishing of mill carbon or chemical cleaning to remove the metal foil surface oxide layer.Operation 6, operation 7, operation 8 are the pad pastings in the conventional mask-making technology, exposure is developed.Operation 9, etched figure, etching host is acidic oxidation copper, the pH value of necessary strict control etching solution, Baume degrees, etch temperature, etching speed finally allows the side etching quantity of figure be controlled at less than in the 0.03mm.Operation 10, electroplating bright copper, plating bath host is copper sulphate, adds brightener.But necessarily require the direction swing of the parallel aperture of negative electrode, air stirring.Nickel plating host is nickelous sulfate, also should have negative electrode to be parallel to the swing of aperture direction.Operation 11, the metal forming figure is pasted on the screen of fabric, entirely is placed on the metal forming figure on the plate glass, allow screen of fabric smoothly press above the big metal forming, use 107 glue, frictioning graph area around the metal forming, frictioning on screen of fabric allows solation go between silk screen and the metal forming.Air dry 2 hours.Be noted that especially and when frictioning, necessarily scrape evenly, allow metal forming and screen of fabric form a smooth entity.At last, cut out the screen of fabric of metal forming graph area.Operation 12, the net that stretches tight is posted on the aluminium alloy screen frame.Net air pressure 8kg/cm stretches tight
2To 10kg/cm
2, with 107 glue screen of fabric being attached on the screen frame, drying is 3 hours under the maintenance air pressure.Operation 13 is pasted protective tapes, partly sticks the polyester Pressure sensitive adhesive tape beyond the metal forming figure.
Capital equipment required for the present invention is a laminator, exposure machine, developing machine, etching machine, the net system that stretches tight, plating copper and mickel equipment.
Produce the half tone that satisfies the production requirement of surface mounting technology printed solder paste fully by the inventive method, dropped into ordinary production already.
