BQC offers full turnkey project solution services---box build, from PCBA quick turn prototyping,PCBA SMT THT assembly to final product assembly, including components purchasing. We can also accept the components supplied by our customers or buy those components from the suppliers named by our customers. After the components arrive at our factory, they should be confirmed and tested by our IQC. Every part need to be recorded in our ERP system, so that every components'quality would be assured for the guaranty of our product

Our advantage
1)maintain or enhance the quality of the premise of a substantial price reduction of 10-30%
2)Significantly shorten Lead-Time
To find substituted component to shorten lead-time Prepare safety stock for the long lead-time components according to customer’s orders forecast
3) supporting from ODM team technical

Component control

1.Components selection
1)Customer assigned brand:use the appointed brand and model only
2)Not assigned parts: use alternative parts after customer's approval, and on the premise that no compromise of quality

2.Procurement policy
1)Standard part mass order, like IC, will only use authorized agents from original manufacturer's official website
2)Standard part low volume or rush order: digikey、 element
3)Unique part like PCB, will choose top 10 suppliers in Shenzhen, etc.
4)Compare price from 8 suppliers, to make sure get reasonal best price.

3.Component substitution
1) in what stage BQC helps customers to find substitution of components
Mature Product: when customers encounter competition pressure
Design stage: when customer’s R&D engineer begins to design the product

2)How to choose substituted brand/manufacturer for components
?IC: Select world famous brands
?Transistor: Select Taiwan listed companies or China mainland listed companies whose history is more than 15 years
?Other custom parts: select the factory who was audited by world-renowned enterprise and has more than 15 years history.

3)Substitution process
A.Substitution process for common components other than ICs
?The purchasing staff looks for the corresponding supplier's engineers to find alternative materials
?R & D hardware, component engineers confirm datasheet and test samples
?Customer confirm the datasheet and test samples

B.Substitution process for IC
?Purchasing department component engineer looks for the corresponding supplier's engineers to find alternative materials
?hardware, component engineers confirm datasheet and test samples
?Customer confirm the datasheet and test samples

4.Components inspection
1) Sample stage:When there is new part, product engineer will strictly inspect every part according to component datasheet.

2)mass order procurement:IQC inspection according MIL-STD-105E sampling inspection class II standard

OEM delivery management
1.Project team
For each customer, there is a project team& QQ group When problems come out, responsible person must reply in 30 min
2.Material delivery
More than 60 quality suppliers with over 10 years experiences
Each material has more than 3 suppliers

3.Production schedule
Make the standard work time in each work station.
By pre-processing parts, making fixtures, or optimizing populating program to improve working procedure.

Continuous improvement in quality
1. After BQC finish the samples, we will find if have problems in materials, PCB layout, production process and test, if have, we will propose the correct action and remind customers to improve
2. After each batch of mass production, we will find if have problems in materials, PCB layout, production process and test, if have, we will propose the correct action. Besides, digging out hidden problems of quality and propose the correct action
