What is The Shengyi S1141 Laminate?
Shengyi S1141 laminates are specialized materials utilized for covering and bonding layers of printed circuit boards. In the distinct case of Shengyi pcb laminates, the transition temperature of the material is precisely 140 degrees centigrade. These laminates possess unique characteristics that significantly enhance their performance, thereby enabling the creation of highly efficient machinery.
Their unique characteristic features render them invaluable at various levels for performing different functions. It is also of utmost importance to examine the thermal stress of Shengyi S1141 laminates in both etched and unetched states. Similar results of 60 seconds without delamination can be obtained, which serves as evidence of the use of Shengyi S1141 laminates. The Shengyi S1141 laminates can be employed in a diverse range of applications.
In this context, the maximum bending point of Shengyi pcb laminates and their flexural capabilities need to be tested. Under A treatment conditions, the laminates exhibit a flexural strength of LW 600 MPa and CW 500 MPa. Additionally, it is crucial to consider the peel strength with one ounce of copper at 288 degrees centigrade for 10 seconds. This allows for an understanding of the point at which the adhesive force of Shengyi S1141 laminates begins to degrade. Therefore，Not suggested for ＞2oz copper, HDI, and≥12L application. For applications with CAF requirements, recommend customer to carry a systematic assessment of its reliability.
