Definitions

  • the present invention relates to the field of printed circuit boards (PCB's). More specifically, the present invention relates to a UN curable legend ink for printing on PCB's using an ink jet printer.
  • PCB serve to interface and connect the various components in electronic devices.
  • the production of a PCB is a multi-step process that includes marking the PCB with a legend showing the location of each part on the board, the identification number, and the polarity of the part. Other markings may also be necessary.
  • the PCB legend is formed through screen-printing, using a screen stencil and a curable (heat, UV, or EB) ink that is pressed through the stencil.
  • Screen-printing requires making a new stencil for printing every type of printed board. Therefore, in the case of printed boards produced in a small lot, the printing cost per printed circuit board is greatly increased.
  • Screen-printing has other disadvantages such as the minimal achievable pitch i.e. inability to produce legible characters of small dimensions (e.g. 0.5mm characters).
  • Inkjet printing provides an ideal solution to the aforementioned problems.
  • Ink jet printing is a process whereby an image is printed directly from an electronic file onto a substrate, without contact between the printing device and the substrate. Printing occurs via projection of a stream of ink droplets to a surface while controlling the direction of the stream so that the droplets are caused to form the desired printed image on the surface.
  • An ink jet printer for use in printing legends on printed circuit boards is described in PCT/ILO 1/00596, entitled, "Jet Print Apparatus and Method for Printed Circuit Board Manufacture".
  • Inkjet printing of PCB's provides the following advantages: (1) there is no need to produce a stencil for each type of PCB; (2) direct digital printing enables digital compensation and correction of distortion of the PCB; (3) the demanding step of placing the screen over the PCB (in screen printing) is avoided; (4) small characters, not legible using screen printing, may be printed by the precise drop placement of ink jet printing.
  • inks for PCB's are typically viscous pastes which are comprised of curable polymers, oligomers, monomers, and solid particulate fillers with particle size of about 5 microns. These inks are not appropriate for use in an ink jet printer.
  • An ink jet ink needs to have an appropriate viscosity and surface tension in order to enable jetting.
  • the ink must have a particle size small enough so as to enable passage through the ink jet nozzle without clogging.
  • the printed legend must be able to withstand immersion in a solder bath of about 250 deg. C without yellowing. In general, the legend must conform to the standards set out in IPC-TM-650 test methods (the Institute for Interconnecting and Packaging Electronic Circuits) and to legibility guidelines set out in IPC-A600.
  • ink jet inks form a solid layer on the substrate after printing, by evaporation of the solvent in which the pigment is dispersed, or by using a phase change ink, or by UV curing while using suitable monomers and oligomers.
  • conventional ink jet inks which are designed for graphic arts or even for textile, are not suitable for printing onto PCB surfaces, due to the very extreme conditions which the printed pattern is exposed to, such as very high temperatures in the solder bath, or presence of very aggressive solvents, which could dissolve the printed pattern, or could decrease the adhesion of the printed legend to the PCB.
  • U.S. Patent No. 5,270,368 discloses a UV curable ink composition for printing an etch resist pattern on a copper clad board.
  • the ink is comprised of at least 8% of an acrylate containing a pendant carboxylic group to enable stripping by a basic solution. This makes the ink unsuitable for legend printing, as the legend is permanent and therefore needs to be impervious to various forms of chemical attack. Furthermore, the low viscosity at 25°C (1-10 cp) hastens the settling of the ink pigments, thus appreciably shortening the shelf life of the ink.
  • Typical UV curable inks such as the type disclosed in U.S. Pat. No. 6,114,406, describing a radiation curable ink composition, have a pigment loading of up to 10%. Higher pigment loading tends to interfere with curing of the films because of light scattering and absorption. However, the relatively low pigment loading typical of inks used in graphic arts, particularly in the case of white pigments, does not yield a sufficiently opaque printing that is acceptable for printing the legend on the PCB.
  • An additional drawback of commonly available UV curable ink jet inks is that they are not designed to withstand the high temperatures (up to 260°C) which the ink must be able to withstand for limited periods of time.
  • the object of the present invention to provide a UV ink for ink jet printing onto PCB's that overcomes the aforementioned problems including those associated with the extreme conditions which the PCB and the printed legend are exposed to, and also overcomes the problem of settling of the pigment.
  • the ink has the advantage of having a low viscosity at high temperatures and a high viscosity at room temperature, thus enabling good jetting from the print head (which requires low viscosity).
  • the ink of the present invention meets the PCB legend ink test requirements of the ICP and displays excellent adhesion to the printed circuit board.
  • the ink also exhibits resistance to various solvents that are part of the flux composition (e.g. iso-propyl alcohol), is very stable at high temperatures, and can withstand even dipping in a solder bath of 250-260°C.
  • the present invention relates to an Ultra violet (UV) curable ink composition for printing a legend on printed circuit boards using an ink jet printer, comprising at least one reactive oligomer, a pigment, at least one reactive monomer, at least one photoinitiator, at least one additive, and at least one dispersing agent.
  • the oligomers and monomers are selected in such a way, that the resulting inks, which are stable dispersions, prior to curing, have a high viscosity at room temperature (about 60- 200 centipoise), and low viscosity (aboutl0-20 cps) at higher temperature, which is set to be the jetting temperature (the temperature in which the printhead operates), between 50-80°C.
  • the ink is heated when it comes into the printhead, thus enabling good jetting.
  • This rehological profile prevents sedimentation of the pigments in the ink during storage, minimize surface defects of the printed legends due to pigment separation, and contributes to fixation of the ink droplet on the PCB during the printing process.
  • the oligomer and monomer mixture are chosen in such a way that the rehological profile is obtained without the use of nonreactive diluents (solvents) leading to an ink that is close to 100% solids (preferably, above 90% solids, "solids” referring to the material retained in the completely curd ink when exposed to temperatures of 100C for 1 hour).
  • the concentration of the oligomer and monomer are selected in order to achieve optimal overall viscosity and surface tension.
  • the oligomers and monomers are chosen in such a way that they are able to withstand the extreme conditions required, particularly dipping in a solder bath at 260°C with no yellowing or damage to the print. Furthermore, the monomers are chosen so as to adhere and promote adhesion particularly to inert smooth surfaces such as exhibited by glossy soldermask found on the outer layer of some types of PCB.
  • the pigment has a particle size of less than 2 microns. This facilitates jetting without the ink clogging the printer nozzles.
  • the pigment has a particle size of less than 0.4 microns.
  • the pigment may comprise organic or inorganic particles, depending on the required color.
  • the pigment is present in an amount of about 10-35% by weight of the ink composition.
  • the pigment comprises one or more metal oxides (for example, iron oxide particles, titanium dioxide particles, or titanium dioxide coated with functional groups) and the concentration of the pigment is selected in such a way which enables obtaining the required curing characteristics and also the proper hiding power and optical density.
  • the preferred pigment is titanium dioxide, having a particle size in the range of 0.17-0.3 micrometer, and weight concentration of about 10-35%.
  • the ink may contain, in addition to the pigment, functional fillers (often called “extenders”), such as fumed silica, clays and zeolites.
