T/T IN ADVANCE (Pay at time of order placement via wire transfer)
How to Ship Electronic Components?
We take great care when shipping electronics overseas. Both the U.S. and U.K. governments have imposed restrictions on air transport of electronics, according to the International Air Transport Association.
1. Understand the shipping rules of the destination country
Different countries have different regulations for shipping electronic equipment, check for certain certifications, and read the destination country's guidelines before shipping to prevent delays or confiscation of goods by customs.
2. Choose a reliable express logistics provider
From providing pick-up service to checking the status with real-time order number, conveniently track packages. At present, the logistics providers we cooperate with more include DHL, UPS, Fedex, TXT.
Of course, if you have a long-term cooperative freight forwarder or your own company's logistics account, you can pick up the goods directly from our warehouse
3. How much does it cost to ship the electronic components?
The shipping cost of electronic products depends on the size and weight of the package and the shipping distance. You can first ask us about the size/weight of the products we sell to estimate the shipping cost.
4. How long does it take to ship the electronic components?
If electronic component in stock, it is usually shipped before 5 o'clock on the same day, and it usually takes 5-10 working days to complete it by international express.
If it is a scheduled component, it needs to wait for the arrival of the parts, and then it will be inspected before delivery. If there are special circumstances, the sales staff will confirm with you. Weekends and holidays will also affect the delivery time of electronic products.
1. We provide 365 days warranty for all electronic components.
2. If you need a test report, please let us know. We have a long-term cooperative testing laboratory. If you have familiar testing laboratory, we can also ship to your designated laboratory for testing.
3. Where does Aztec Electronics mainly purchase electronic components from?
Distributors, free market, 48 global large-scale OEM factories in close contact with us (Great Price advantage, 100% original)
2.Are the Texas Instruments Incorporated (TI)'s CD74HC688E price and stock displayed on the website accurate?
Aztec Electronics inventory fluctuates greatly and cannot be updated in time, it is recommended to confirm the order with Aztec Electronics salesperson or online customer service before payment.

- How to test electronic components and quality inspections?
- How to transport your electronic components safely?
Need Any Service, please feel free contact us.
After the electronic components have passed the quality inspection of Aztec Electronics, there are generally the following five packaging forms for electronic components: Tape, Tube, Tray, Bulk and Ammo.
Tape/Reel | Tube | Tray | Bulk | Ammo |
Weave bulk chips into tapes and pack them into reels through SMD components packaging Tape Machine. Reel is the most commonly used. | When packaging, arrange the components in the same direction and put them into plastic tubes one at a time. | Choose tray package with the same specifications as the original manufacturer, put the components into the tray and use the strapping machine. | Bulk packaging means that the SMD components are freely packaged in a formed plastic box or bag. | Adhesive tape cut continuously in predetermined quantities. The cut strips are placed in boxes for safekeeping. |
Choose electronic components that are vacuum-sealed against water, dust, moisture, oxidation, corrosion, and even UV or RF pollution.
How to pack electronic components in cartons?
1. Choose the right box for your electronic components2. Use anti-static bubble film protect electronic component
3. Put it into the box, no buffer dead corner, 360-degree package.
4. Labeled as fragile to ensure that the courier knows what needs to be done with the package.
