PCBA manufacturing cost in the total cost of electronic equipment has been a major part of the input, because it is the core components of electronic equipment, from the programme design, research and development cycle on the cost is also very large, how to choose a way to save PCBA manufacturing and processing costs for customers is very important.
As has been established for more than ten years of PCBA manufacturingplant, we have some of our own insights into the cost control of the entire PCBA manufacturing process, take this opportunity to share with the majority of customers briefly.
PCBA manufacturing
1.PCBA manufacturing small quantities, you can choose a professional sampling manufacturer. Ancient saying: ‘There are first and foremost, there are specialities in the field of science and technology.’ Then do each manufacturer has its own positioning, if the volume is not large, as far as possible, choose to do professional sampling, fast, efficient,price advantage.
2.Components procurement as far as possible to choose the futures supplier, or with pcba manufacturer docking time first understand clearly, their procurement channel is to spot for the main or futures for the main. If it is to do futures of the whole batch purchase price will be lower, spot although fast but the price will be high. It makes sense that component availability and cost are also affected by component (non-)availability.
3.PCBA manufacturing costs have many aspects, the more worrying part of the main PCB light board information.Circuit board manufacturing technology selection. The mainstream FR-4 immersion gold plate / gold-plated plate prices are not the same, if the engineering process does not have particularly large requirements in the choice of material to try to choose conventional materials, such as: Rogers material substrate, not only need to be a month in advance for the booking, but also the subsequent processing requirements and costs are much higher.
PCB process: through-hole, material, surface treatment, often PCB process cost is also a major expense in the whole manufacturing process.
Single-sided circuit boards / double-sided circuit boards / multi-layer circuit boards: mainly refers to the single-sided paste or double-sided paste, single-sided paste only one side, the cost is much lower than the double-sided panel.
Number of pads: The cost is usually increased with the number of pads required.
4.PCBA assembly test session evaluation. Assembly test session there are many factories are to be charged separately, some are discounted into the processing fee, as far as we know, many PCBA manufacturing plants are operating in this way, in the signing of the contract to understand clearly. Testing costs: ICT circuit test, aging test, high and low temperature test, optical signal transmission test, shock test and so on.
5.Three-proof paint: There are two ways in this section, three-proof paint spraying machine and manual coating. Three-proof paint spraying machine mainly produces spraying man-hours and data costs. Manual coating mainly incurs the cost of labour hours and consumables.
6.Certification and standards: Many industries need to do the corresponding qualification accreditation according to the prevailing standards of the product, such as medical PCBA needs ISO13485, automotive electronics PCBA needs IATF16949, or need to do for the product to comply with the RoHS certification of the PCBA, or need to do for the product to comply with the RoHS certification of the PCBA, or need to do for the product to comply with the RoHS certification. PCBA RoHS certification, IPC-A-610D level requirements, etc. will add time and financial costs.
The above points are to save PCBA manufacturing costs of the main links, there are many auxiliary materials can also be considered into the link, but the quality of the auxiliary materials is still very critical, a penny a penny, this is still to pay attention to some of the.
