LGS300 graphite thermal pad is a new thermal interface material. It transfers heat along the two directions, shielding heat source and components meanwhile improving the performance of consumer electronics products. The thermal impedance of LGS is very small and can completely replace the high performance thermal grease while avoiding the shortcoming of poor and dirty thermal grease process. LGS thermal conductivity is three-dimensional, that is not only it can transfer heat between the heat source and the radiator in the vertical direction, but also in the vertical direction, which ensures that it can quickly transfer heat out in vertical direction when the partial heat is high.
Therefore, LGS thermal film is very suitable in the small space to efficiently transfer heat generated by heat source.

Q1: What thermal conductivity test method was used to achieve the values given on the data sheets?
A1: A test fixture is utilized that meets the specifications outlined
in DRL-III.
Q2: Is GAP PAD offered with an adhesive?
A2: Currently, All GAP PAD Materials have inherent tack.
Q3: Is the adhesive reuse?
A3: Depending on the surface being applied to, if care is taken, the pad may be reuse. Special care should be taken.When removing
the pad from aluminum or anodized surfaces to avoid tearing or delamination.
Q4: What is meant by “natural tack”?
A4: The characteristic of the rubber itself has a natural inherent tack, with the addition of an adhesive. As with adhesive backed
products, the surfaces with natural tack may help in the assembly process to temporarily hold the pad in place while the
application is being assembled. Unlike adhesive backed products, inherent tack does not have a thermal penalty since the rubber
itself has the tack. Tack strength varies from one GAP PAD product to the next.
Q5: Can GAP PAD with natural tack be repositioned?
A5: Depending on the material that the pad is applied to, in most cases they are repositionable. Care should be taken when
removing the pad from aluminum or anodized surfaces to avoid tearing or delaminating the pad. The side with the natural tack is
always easier to reposition than an adhesive side.
Q6: Is GAP PAD reworkable?
A6: Depending on the application and the pad being used, GAP PAD has been reworked in the past. Some of our customers are
currently using the same pad for reassembling their applications after burn-in processes and after fieldwork repairs. However,this
is left up to the design engineer’s judgment as to whether or not the GAP PAD will withstand reuse.
Q7: Will heat make the material softer?
A7: From -40°C to 200°C, there is no significant variance in hardness for silicone GAP PAD Materials and Gap Fillers.
Q8: What is the shelf life of GAP PAD?
A8: Shelf life for most GAP PAD Materials is ten (10) year after the date of manufacture. For GAP PAD with adhesive, the shelf
life is two (2) years from the date of manufacture. After these dates, inherent tack and adhesive properties should be
recharacterized. The GAP PAD material’s long-term stability is not the limiter on the shelf life; it is related to the adhesion or
“age up” of the GAP PAD to the liner. Or in the case of a GAP PAD with adhesive, the shelf life is determined by how the adhesive
ages up to the removable liner.
Q9: How is extraction testing performed?
A9: The test method used is the Soxhlet Extraction Method;
Q10: What is the thickness tolerance of your pads?
A10: The thickness tolerance is ±0.2mm on materials .
Q11: What are the upper processing temperature limits for GAP PAD and for how long can GAP PAD be exposed to them?
A11: GAP PAD in general can be exposed to temporary processing temperatures of 120°C.Time base on GAP PAD thickness, assembly line
14 meters long,time about 10-15 minutes .
