UnityPCB’s 12,400㎡ facility includes a 2,600㎡ clean room, 5 SMT lines, and 3 DIP production lines. Equipped with precision drilling machines, plating systems, and etching setups for exact circuit patterning, as well as reflow soldering machines and wave soldering systems. Our state-of-the-art X-Ray and AOI machines ensure the high-quality PCB production.
This type of PCB has the capability to withstand high temperatures up to 170°C, it is applied in use situations that experience higher temperatures
These materials include the High Tg FR-4, Isola 370 HR, Rogers 4350B, Nelco N4000-13, Taconic TLY, Panasonic R-1755, Ventec VT-4B and TUC TU-883.
The thermal conductivity of High Tg circuit boards is much higher than that of standard PCBs due to the higher thermal resistance of Tg substrates.
Yes, at UnityPCB we provide support in the design and engineering process to ensure your High Tg PCB design can effectively be manufacturing and performs in the intended manner.
Available surface finishes include HASL, HASL Lead-Free, ENIG, Immersion Silver, Immersion Tin, and OSP.
The turn around time for High Tg PCBs can take a bit longer and normally takes between one and two weeks depending on the order forms complexity and the quantity ordered.
