Silicone for junction coating resins

Typical Applications of liquid silicone junction coating resins

Liq­uid sil­i­cone junc­tion coat­ing resins are designed for cov­er­ing diode, tran­sis­tor, and rec­ti­fi­er junc­tions. These resins pro­vide a 100% solids coat­ing and our rigid qual­i­ty con­trol guar­an­tees ion­ic puri­ty lev­els of max­i­mum 1 ppm.

CAPLINQ presents Lin­qSil LSC junc­tion coat­ing resins, which include Lin­qSil LSC 100, a one part junc­tion coat­ing, and Lin­qSil LSC 200, a two-part junc­tion coat­ing. These coat­ings will pre­vent elec­tri­cal break­down, sta­bi­lize peak inverse volt­age, min­i­mize junc­tion sur­face leak­age, and pro­vide envi­ron­men­tal pro­tec­tion for high tem­per­a­ture performance.

Typ­i­cal appli­ca­tions of these junc­tion coat­ing resins include elec­tri­cal and mechan­i­cal insu­la­tion pri­or to plas­tic mold­ing, pro­tec­tive coat­ings over hybrid inte­grat­ed cir­cuits, and her­met­ic-type pas­si­va­tion of semiconductors.

Other applications of liquid silicone resins in various devices are stated below:

  • 1. GTO Thyris­tor Coating
    A GTO is a four lay­er switch­ing device that is used in elec­tron­ic cir­cuits to turn it on or off by apply­ing a short gate pulse to it. liq­uid sil­i­cones for junc­tion coat­ing resins is done in the GTO thyris­tor cir­cuit to make it mois­ture resis­tant and a sta­ble heat device.
  • 2. Hybrid IC Chip Coating
    A hybrid inte­grat­ed cir­cuit is an elec­tron­ic cir­cuit that is con­struct­ed of var­i­ous semi­con­duc­tor devices- tran­sis­tors, diodes, induc­tor, resis­tors, and capac­i­tors bond­ed to a sub­strate board. The hybrid IC chip coat­ing is done to pre­vent the chip dam­age dur­ing potting.
  • 3. LCD Elec­trode Pro­tec­tion Coating
    LCD elec­trodes are used in pan­el dis­plays that use the light mod­u­lat­ing prop­er­ties of the liq­uid crys­tal to dis­play images in mono­chrome or col­or. Liq­uid sil­i­cone junc­tion coat­ing resins is used for cir­cuit pro­tec­tion, and to pro­vide elec­tri­cal and mechan­i­cal insu­la­tion before plas­tic molding.
  • 4. Pho­to Diode Coating
    The pho­to­di­ode is a semi­con­duc­tor device that con­verts light into elec­tri­cal cur­rent based on the pho­tons absorbed by it.
    The liq­uid sil­i­cone coat­ing is used to sta­bi­lize peak inverse volt­age, as apply­ing a reverse volt­age to a pho­to­di­ode caus­es severe dam­age to the device performance.
  • 5. Ther­mal Head Coating
    Ther­mal coat­ings are applied to the metal­lic sur­faces, which are oper­at­ed at ele­vat­ed tem­per­a­tures in the form of exhaust heat man­age­ment. The liq­uid sil­i­cone junc­tion coat­ing resins are applied to pro­vide envi­ron­men­tal pro­tec­tion for high-tem­per­a­ture per­for­mance and ther­mal cycling.
