Conductive carbon paste CCI-305LH

 

CCI-305LH type conductive carbon paste Senndai Electronic Materials Co., Ltd. is a wear resistant low-resistance carbon paste. It is made of special resin lapping and refined toner is made. Suitable for screen printing, mainly used in single-sided circuit board (PCB) in the printed circuit, the through-hole buttons and bridge. In FR2, FR4, copper film, glass, ceramics and nickel coating surface with good printability, abrasion resistance, solvent resistance, high temperature resistance and high hardness and strong adhesion.

First, the performance indicators
1, packing: Toner
2, a solid content (WT%) 60-65%
3, a density (g / cm3) 1.2-1.3
4, the viscosity (dpa.s20%) 200-500 (VT-04E viscosity detector)
5, the coating area (cm2 / g) (depending on the film thickness) 100-200
6, square resistance (Ω / □ / 25.4цm) ≤20
7, adhesion (3M600 tape, vertical pull) with no loss
8, hardness> 5H
9, heat resistance (75 ℃ 1000hr) ± 10%
10, temperature characteristics (40 ℃ 95 ℃ RH 1000hr) ± 15%
11, high temperature 260 ℃ can be resistant to more than 15 seconds
12, ultrasonic cleaning resistance, no cracks
Second, the use
1, the substrate FR2, FR4 copper-plated nickel coating film;
2, wire mesh stainless steel wire mesh or polyester screen printing;
3, diluent diluted with CCI-305LX dedicated carbon paste;
4, the curing process (recommended) oven 150 ℃ 30-45 minutes, IR; 175 ℃ 7-10 minutes
5, cleaning agents cyclohexanone; alcohol;
6, the storage room temperature storage, unopened storage period at six months or more; (should avoid high temperature, high humidity preservation)
7, packaging 1.00 kg (or according to requirements)
Third, the operation and safety
1, using the metric or imperial 40-120T 100-305 mesh polyester or stainless steel screen printing, squeegee hardness of 65-80 degrees.
2. Stir thoroughly before use.
3, printing substrate must deal with clean, such as residual oil, oxides, thermoplastic resin, hand sweat and other contaminants when will severely reduce adhesion and electrical properties.
4, there must be enough carbon paste printing, otherwise it will affect the printing performance and carbon print thickness, resulting in changes in resistance.
5. In order to ensure consistent performance carbon printing should try to maintain the same viscosity; plus diluent should be mixed with the carbon paste close up some of the new carbon slurry, then an appropriate amount (1-5%) were added after special carbon slurry diluent , stir evenly.
6, to be completely cured, otherwise it is impossible to obtain the desired properties, curing conditions depending on equipment required for fine-tuning.
7, CCI-305LH conductive carbon paste containing a solution, should be kept well ventilated to prevent excess vapor inhalation, such as contact with the skin, should be promptly wash with water and soap, please do not go near the fire.
