CALCULATION EQUATION FOR 1 CHIP SOLDERING COST IN SMT PROCESS.

You said:

"how come do i calculate the money for one chip mounting. I really want to know that. Maybe someone already has it. Shortly speaking , CALCULATION EQUATION FOR 1 CHIP MOUNTING COST IN SMT PROCESS."

So, I gave you equations for calculating that. Providing more detail:

Cost = Labor + Production Materials + Overhead

Labor = (Time To Set-Up + Time For Task) * Labor Rate * Benefits).

Time To Set-Up = Non-recurring time involved in preparing to do a job. Here, I assumed set-up was zero. You could add work instruction preparation and things like that.

Time For Task = Recurring time involved in doing a job. Here, I figured it takes about 6 second to solder a chip component to a board by hand. And, I assumed quality inspection time to be zero.

Labor Rate = Base salary for work performing task. Here, I guessed at $10 per hour. Your accounting people would know the specific number for your company.

Benefits = Sum of Annual Benefits (ie, vacation, paid sick time and insurance, etc) Costs / Hours Worked Per Year. This should be calculated on a large number of workers. Here, I guessed that these costs were $3 per hour. Your accounting people would know the specific number for your company.

Production Materials = I assumed this to be zero, but you could calculate the amount of solder used, if you wanted to drill-down for more detail. Here, I also assumed no-clean paste was acceptable.

Overhead = Sum Of The Annual Plant Operating (ie, rent, gas, electric, water, capital costs, salaries and benefits for non-hands-on workers, etc) Costs / Hours Worked Per Year. This should be calculated on a large number of workers. Here, I guessed that this doubled all other costs. Your accounting people would know the specific number for your company.
