These are the top four criteria that consumers look for in PCB assembly suppliers. Among all of these factors, “how much the PCB assembly project will cost” is typically the one that consumers are most concerned about. Although the majority of manufacturers assert that they provide infallible goods, rapid turn-around times, and unmatched service, the consumer ultimately bases their decision on the price they are given. Customers will naturally turn to alternative service providers that are prepared to do the job at a lower cost while maintaining the greatest quality if a manufacturer quotes a high price. As internet business and trade have developed, almost all of the top Pcba quote online continue to keep an “Online Quote” feature on their websites. What is the purpose of this online quotation form? What are the form’s primary PCB assembly cost breakdown fields? How does it benefit the client? For more information, see the post.
Required Fields to Complete to Receive a Cost Estimate
Prototype and low-to-mid-volume assembly orders are covered by the PCB assembly quotation. Some of the major cost factors, including the following, are included in the PCB assembly quotation online form. (Note: To get an estimate of the breakdown of PCB assembly costs, all fields must be correctly filled in.)
Arrangement Type: There are several sorts of assemblies that are used in PCB manufacture. Surface Mount (SMT), Through Hole (THA), and Mixed (both) are only a handful of them. The kind of assembly you want must be specified when filling out the estimate since each form of assembly has a different cost.
Materials: Project to project has different choices for materials. Mention the kind of substrate you’ll need to construct your PCBs under the preferred materials tab in the PCB assembly cost breakdown form, such as FR-4, Aluminum, Copper, Polyimide, high frequency (Rogers, PTEE, PI), etc. Once again, the price of one substance varies from that of another. Consequently, the material you have selected will undoubtedly affect the total cost of manufacture.
Layers: Alternating layers of various materials are used to create PCBs according to the needs of the application. PCBs might have two layers or as many as fourteen. The complexity of manufacturing and associated costs will increase as layer count increases.
Placement of Components: One of the main factors affecting cost is whether you need double-sided assembly or only top-layer assembly.
Procedures Needed: PCB assembly covers a variety of simple to intricate procedures. Among these, a handful is as follows:
- Pick and place SMT
- auto-through hole insertion
- Slide line through a hole
- swivel solder
- discerning solder
- Hand soldering
- general meeting
Every PCB manufacturing project calls for unique procedures. The types of procedures needed for the assembly depend on the materials used, the application region, the assembly technique, etc.
Cost of PCB Assembly Breakdown
Surface Finish: Surface finish specifications vary depending on the job. The kind of finishing needed for a board depends on factors including assembly technique, application area, and environment. Filling up this field is thus very important. Decide between hot air solder leveling, lead-free HASL, immersion Gold/Tin, electroless Nickel, and other options.
Choose your chosen color from green, red, yellow, blue, white, black, purple, matte black, and matte green for the solder mask.
Assembly Compliance Requirement: For certain applications, PCBs must be produced under specific standards. This need must be known by the manufacturers before determining the cost of PCB assembly. Among the many widely used standards are IPC-A-610D Class I, II, or III, RoHS (lead-free), Non-RoHS (led), and ITAR.
Test prerequisites: Indicate the kind of testing the PCB boards must go through. This comprises, among other things, the power-up, functioning, In Circuit Test (ICT), thermal cycling, X-ray, and visual inspection. It is crucial to include in the quotation form that each test has a distinct pricing structure because of this.
Some PCB assembly manufacturers need their clients to fill out unique packaging needs, shipping needs, and other criteria. Additionally, they give a section for you to fill out any other unique criteria not already included in the form. The manufacturers take their time to thoroughly grasp the requirements after receiving a full quotation form, and they then project a budget to finish the PCB assembly job. With a few small exceptions, the original cost mentioned usually doesn’t alter. Make advantage of the online quotation feature offered by the manufacturer the next time you are approaching them with a PCB project. This enables you to get a cost estimate and prepare your budget. You can also submit online quote requests to two or three Pcba quote online and collaborate with the company that offers the lowest price. To get a PCB Assembly cost breakdown, customers should contact only reputable manufacturers like Sierra Assembly Technology, who have a proper PCB Assembly quote and cost calculator page on their website.
