Large and bulky 3-dimensional shapes cause issues for designers. These designs use excessive amounts of space to accommodate the wire, central core and mounting hardware. Heat transfer is poor due to the difficulty in thermally coupling the cylindrical shape to standard heat sinks. High resistances can only be achieved through excessively long wires or through extremely thin wires-neither of which is desirable. The majority of wound resistors are spiral wound and add inductance to the circuit that may be unacceptable. Inductance be reduced by special winding techniques but this adds cost to the resistor.
Thick film heaters and resistors are generally flat 2-dimensional shapes as thin as 0.010” thick, which offer a low profile. This minimizes the space requirements and is inherently better for thermal coupling to flat heat sinks, circuit boards and bulk heads. The thick film pastes come in a variety of resistance values so resistors from less than 1 to many Giga Ohms can be produced. This variety also allows tailoring of the resistance traces to accommodate the surface area available and optimize the amount of thermal coupling to transfer heat. The printed pattern allows opportunities to reduce/eliminate added electrical inductance inherent in wound resistors that may be unacceptable.
We worked with the crew at Thick Film on a few different projects over the period of two years and found them to be creative problems solvers, responsive to our needs and concerns and professional in every way. We would use their services again and would recommend them to others needing their services
We enjoy working with TFT because they are very responsive to technical inquiries and are proactive in finding solutions to design challenges, even ones that we have not foreseen — TFT has always made me feel that we are working together on the same team. In addition, they are very conscientious about delivery time and the end product is of very high quality.
We have worked with the team at Thick Film Technologies on several international consulting projects and have found them to be professional, responsive and effective. We intend to maintain and expand our relationship and would not hesitate recommending them to anyone.
Thick Film technology has made its way into microwave applications to relatively high frequencies. Using special techniques to conform to specifications especially in calibration components. The process is also very cost effective.
We have worked with Thick Film Technologies on several potentially high volume projects and have found them to be professional, customer centered and proactive problem solvers and communicators. We are currently working with them on another high volume project requiring coordination among 4 different customer sites including the UK, Singapore and two sites in the US. We are happy to have them on our team.
