Hoeveel kost PCB-assemblage

Geplaatst op 06-07-2020

Hoe worden de PCBA-verwerkingskosten berekend? Hoeveel is het?

De berekening van PCB-assemblageen verwerkingsprijzen hebben in feite uniforme offerteregels in de branche. Omvat voornamelijk fabricagekosten van printplaten, aanschafkosten van componenten, assemblagekosten, engineeringkosten, testkosten en daaropvolgende logistieke inklaringsservicekosten, enz. Productiekosten van printplaten, testen van vliegende sondes, printplaat engineeringkosten worden opgenomen in de fabricagekosten van de printplaat in. Bij de aanschaf van componenten, als gevolg van schijfbelasting zoals weerstanden en condensatoren en SMT-chipverliezen, is het noodzakelijk om ongeveer 5% van de toename van materiaalverlies te dekken; SMT-chipmontagekosten zijn inclusief SMT en DIP-postlassen, enz., Afhankelijk van het lassen op de printplaat. Punten en procesmethoden worden afzonderlijk in rekening gebracht; voor kleine partijen PCBA worden doorgaans engineeringkosten in rekening gebracht, inclusief de kosten van procesdocumenten, staalgaas, SMT-lijnvervanging, enz .; PCBA-testkosten moeten ook worden opgenomen, op basis van de test van elk PCBA-bord. Tijd om te berekenen; Op het gebied van verpakkingslogistiek moeten speciale verpakkingsmaterialen en drie anti-verven de kosten berekenen, daarnaast moeten volgens de transactievoorwaarden van de klant, zoals FOB, extra kosten zoals douanelogistiek worden berekend.

Typical 2016 PCB assembly processing price calculation method formula:

PCBA processing cost = PCB board cost + PCB test fee + PCB engineering fee (for small batches) + component procurement cost (partially floating 5%) + SMT/DIP welding fee + PCBA testing fee + assembly engineering fee (for small batches) +Special packaging and logistics costs (if customer needs)

How to control the cost of PCB assembly?

PCB assembly cost, how to get the best PCB assembly quotation, here are some tips to guide you on how to control the PCB assembly price.

  • Assembly type surface mount (SMT) (SMD component) through-hole (DIP) hybrid (both).
  • Component placement requires only the top-level component to request Doulbe double-sided assembly.
  •  Total number of components (SMD + DIP).
  • Component packaging (reel priority), reel, tubing, tray, cutting strip with or without lead tape, loose packaging bag.
  • The required process SMT chip through hole is automatically inserted into the through hole sliding line wave soldering automatic optical inspection (AOI)< br> X-ray selective solder manual solder assembly.
  • Quantity and batch size. “Keep Panelize flexible to meet the needs of your manufacturer.” You need to make sure that panelization is optimized for the needs of PCB assembly manufacturers.
  •  Preparation requirements for special parts (ie lead length, minimum/maximum height, spacing).
  •  The total cost of the complete bill of materials (BOM).
  • Number of bare board (PCB) layers and materials used. The cost of flexible PCB components is higher than that of rigid PCB boards.
  • Coating requirements (medical or military usually require full coating or selective coating) number of sprayed or brushed coatings-coating area specified by coating tolerance.
  • Potting requirements (if any).
  • Assembly compliance requirements RoHS (lead-free) and non-RoHS (lead-containing) IPC-A-610D I, II or III ITAR.
  • Test requirements (RayMing prefers to test all PCBA boards before shipment, we hope you can tell us how to test) Power-on functional circuit test (ICT) No test for cycling (visual inspection only).
  • Non-standard/special containers for standard ESD (electrostatic discharge) bags required for transportation.
  • Delivery (RayMing provides fast turning PCB assembly service).

How to reduce the scrap rate of PCB assembly?

The above 16 tips will affect the PCB assembly price, so you can choose the best one to save costs, when you purchase parts, you can provide multiple component sources for each component, it is easy to control some costs, some agents There is also a strong price support for a component, which reduces cost sources more quickly.

However, the PCB manufacturing process is very complicated, and reasonable control of the PCB production process will effectively control PCB production costs. Kingford has a perfect PMC department, and the materials management and control, scheduling, production planning, delivery and other links are in order. In addition, the rational use of hydropower is crucial. PCB factories are generally controlled by semi-automation. Machine power consumption and constant temperature and humidity in the SMT workshop produce a lot of consumption every day. It is also important to reduce the scrap rate of PCB assembly.

The scrap rate of PCB assembly can be reduced from the following aspects:

  • Enhance the sense of ownership of all employees, and attach importance to the quality of PCB assembly.
  • Ten tweede is de kwaliteitsafdeling wetenschappelijk en controleert ze strikt de PCB-kwaliteit.
  • De prestaties van de medewerkers zijn rechtstreeks gekoppeld aan het PCBA-kwalificatietarief.
  • Ten vierde moet het senior management bekend zijn met het hele proces van PCBA en over sterke managementcapaciteiten beschikken.

De duurzame ontwikkeling van de PCBA-fabriek is onlosmakelijk verbonden met de oprechte samenwerking van alle leden. Kingford is al meer dan 20 jaar getuige van de samenhang en het kwaliteitsbewustzijn van het bedrijf. Klanten zijn welkom om nemen.
