Surgical Tools useful for Manufacturing

Small Boards, SMT circuits and hybrid electronics need special tools. The soldering and handling require some tools and custom jigs which can be custom designed. 

Some product are mass produced, some tools for managing and working on Tiny PCB's and parts may not be available in the market at an affordable price.

Electronic Product Production Manufacturing

So affordable solution can be created, the jigs are supplemented by surgical tools. These are the Clips and Tweezers that a doctor uses when he conducts an operation.


Surgical Tools useful for Manufacturing

Call it Forceps, Tweezers or Pliers. These tools, both the bent/arched/curved one and straight are useful.

When you go to a Surgical Supplies Store, Buy some Filter Paper, capillary tubes and a spirit lamp as well. These can find a lot of good use in the ultimate quest for the God Particle. Beat the Swiss to it.

Blind Dial Proportional Temperature Controller

This is a Low cost controller, Analog Dial Temperature Controller. It is also called Blind Controller. This essentially means Open Loop, just control the fuel or energy input to the system to regulate heat. This is not a Blind Controller that way, it only cannot display the temperature value, that could be another reason it is called blind.

Blind Temperature Controller

Dial cyclic timers were used to control heat, these were purely mechanical clockwork devices. They could regulate well, when the material flow (liquid) is constant and mains power is regulated. But when the job to be heated, varies in quantity, control temperature is close to ambient or when a precise control is required; closed loop controllers are used. Even a thermostat is like closed loop, as the bimetallic sensor is temperature dependent. But not good enough.

This controller is closed loop, precision controller, only the digital display of temperature is absent. Fine one deg variations may not be easy in this.
