generate faster pcb assembly turnarounds
Fast turnaround is not just a marketing gimmick for world-renowned and most respected tech brands --it\'s a promise.
The PCB prototype assembly is by no means a simple activity and is short in timeconsuming hang-
In an industry, ups can become a customer with lost and angry orders
Hourly turnover is the norm.
In order to be able to reliably produce results in such a short period of time, the PCB assembly plant needs to optimize almost every aspect of its workflow to improve speed and consistency.
The core of this demand is to maximize the assets and resources you already have, or to add an inherent conflict between additional assets and resources to your environment.
Basically, what\'s fast?
What the turnaround PCB fitters want to know is whether they should hire additional help, use their machines more, or buy newer, better machines to make the most of their existing employees.
Before discussing whether or not manpower or machine power will really generate a quick turnaround, we need to make sure that the PCB planning system itself has achieved the best performance.
As William Ho asserted, component placement is a bottleneck for any PCB assembly line.
In essence, this bottleneck consists of two parts.
Component sorting and feeder arrangement.
PCB manufacturers need to select the optimal order of components and then assign them to the appropriate feed rate. The way you can approach the PCB assembly sorting and feeder arrangement is almost infinite.
In a business environment, it is not feasible to find the truly most effective solution --
At least in the current computing technology, and certainly not in twoday timeframe.
PCB fitters use genetic algorithms to determine proximity within a tight time frame-
On the road to a \"perfect\" solution, the optimization planning system will not get lost.
While this is not a problem that today\'s technology can solve, it is important to remember that none of the current PCB assembly processes are very effective.
This is becoming an increasingly complex factor.

More machines mean more set-up time, because we know that any given PCB assembly process cannot be fully effective, so we can make time limits on the workflow process.
SMT machine not plugged-and-play devices.
Even efficient machines require at least an hour of conversion.
If you run eight to ten settings per week, that means you lose a whole day of production each week.
Conversion time can be a major drag on production, especially when dealing with tight turnaround.
Once time is lost, it cannot be recovered, and every second saved can increase revenue.
Since SMT machines may encounter almost unlimited production possibilities in one run and often require multiple runs per day, any conversion time is down time.
According to the SMT machine revenue generation time, UIC is shown in a simple set of charts, calculated every second-
The one-hour downtime for a line that generates $10 million a year is $5000.
While there is always a way to improve the efficiency of the PCB assembly line, there is no way to explain $5000 in unnecessary losses.
Considering that some SMT machines may take four hours to set up in one prototype PCB run, making the most of each working day is a better option.
In addition, the installation of additional production lines will not affect the productivity of each line.
While this seems to help improve PCB assembly turnover, the cost of adding more production lines and workers may exceed its value if the overall production volume does not increase.
For this reason, it would be better to have the worker late or even hire additional shifts.
Night shifts can generate more value and maximize the time that each machine can run, which is the best way to ensure short-term efficiency
PCB assembly project turnover.
Find workers willing to work overtime
Or a whole night shift.
Is one of the best ways to ensure that you always meet the assembly deadline and minimize downtime.
