Why Don’t the PCB Assembly Factory like to take small order
Recently, many customers want to cooperate with our PCB assembly processing factory to request special boards, such as PCB to add process side, mainly used in PCBA. Generally, one side can be added on the top and bottom of the board. .. In order to save the cost of the PCB board, the board is often arranged, just because he sent it without the craft side, I did not pick up the order, so the customer has been looking for me, it looks very urgent, I told the customer that you can Ask other suppliers, maybe they will help you post it. It says that you want to find near Jiuwei, Xixiang, Shenzhen, because our company is near your company, the order is 600,000, the number is really large, but you see,When the price is 0.004RMB, the amount of solder joints of 600,000 is not much. It takes a lot of electricity and labor to open a machine, so there is no profit at all.
At the beginning, we did pick up a lot of such small PCB assembly processing factory orders, NO charge the Openning fee,Powering up and shutting down is very big and wastes time.
So what kind of single is a small order? Less than 8 * 8 electronic circuit board, usually a combination of four small electronic circuit boards, about 85RMB, this order is the smallest, for now,our orders are starting with 600RMB.
The formula for calculating the pcb assembly price is, Price=how many pads * the cost per pad, if the capacitor can not pass the machine, will need to manually solder small batches by own.Small plate solder joints, such as each square CM / 9 solder joints, then each solder joint is about 0.2 yuan, the price will be slightly higher, IC may even count two pads to a point, this depends on pcb assembly processing In the case of the factory, there is a certain difference in the charges for each factory.
In a word, I will give you a detailed calculation.
PCB assembly processing factory, the order is small, so the number of points is small, if the minimum consumption of 300RMB, this order is done, it should be about 1RMB/pcs.
Why are such small orders being picked up, and a few hundred of quantity can make money? It says that I don’t want to pick up, but all of them come from small customers. I heard this sentence and I know that it is a loss money. Loss, what are those? Mainly the preliminary work such as: change the steel mesh, the compoenent board, but also to re-program, PCB positioning, but also provide sample to confirm, such things is waste more labor costs and boot costs are not enough, It is terrible!!
The customer who just said that the amount of 600,000 is basically spent on the preliminary work. After the machine is adjusted, the assembly time is also very short. It will be done soon, and the quality inspector will testing when done and check if there are any false soldering or soldering, and confirm that the board is ok.
Conclusion：PCB Assembly processing factory does not like to pick up small orders because it is not making money, such as labor, machine consumption, shutdown programming, anti-repair, etc… Pre-work, you 600,000 points, no profit…
