Here is the FAQ list for you reference, you are welcome to help us to add the questions into the FAQ list. You also could contact firstname.lastname@example.org if you have any questions/confusions.
1. What kind of shipping Method is available on BokTech?
1). DHL/FEDEX/UPS (Hongkong), Lead-time: 5-7 working days for most places over the world.
2). DHL/FEDEX/UPS (Shenzhen), Lead-time: 3-5 working days for most places over the world.
2. What kind of shipping term does BokTech use?
1). FOB SZ, "Free On Board", is a term in international commercial law specifying at what point respective obligations, costs, and risk involved in the delivery of goods shift from the seller to the buyer. The seller bears all costs and risks up to the point the goods are loaded on board the vessel. On the other hand, the buyer pays cost of marine freight transportation, bill of lading fees, insurance, unloading and transportation cost from the arrival port to destination.
2). EXW, the seller makes the goods available at their premises, or at another named place. The Ex Works term is often used when making an initial quotation for the sale of goods without any costs included. EXW means that a buyer incurs the risks for bringing the goods to their final destination. Either the seller does not load the goods on collecting vehicles and does not clear them for export, or if the seller does load the goods, he does so at buyer's risk and cost.
3. Why do PCB panelization?.
PCB panelization is not to decrease the cost of PCB fabric, basic it increases the cost a little bit as PCB factory need to add the Magin, but it promotes the efficiency of PCB Assembly a lot. If you are going to do PCB assembly by pick and place machine, we recommend to do PCB panelization
4. Why there are series of characters on PCB?
PCB factory fabricates PCBs of different client at the same time, the series of characters is ID of your PCB boards to make sure your PCB are ship to the right guy. If you think it is too obvious, you can add “JLCJLCJLCJLC” to specify the location on PCB. However, if you really want to remove it totally, we can ask our factory to fabricated your PCB separately, but it also double the price.
5. Why the quotation changed after the order is confirmed by BokTech?
Basically, the quotation is not changed, it may change if you have special requirement on your PCB or PCBA design, like the following specification:
1). If the area of PCB is large than 650 sq.com, the unit price will increase.
2). Half-cut / Castellated Holes or blind via design will increase the unit price.
3). If your PCB design have some un-conventional design, like the minimum tracking/spacing is thinner than 6mil, minimum hole size is smaller than 0.3mm, etc. will increase the unit price.
6. Why the lead-time is longer than estimated online.
The lead-time of one project is depend on the lead-time of Component & lead-time of PCB Assemble, you can find a reference here. It may cause delay in following situation:
1). The components purchased on Digikey or Mouser is hold by China custom, especially some ICs.
2). Your project is in peak production season, the PCB Assembly lead-time may prolong a little bit, but not too much.
3). Some design issues or communication issues also prolonged the whole manufacturing process.
7.What is material consumption?
Material consumption is a normal consumption during transport and manufacturing. Normally, if you place the order of 10 pcs sample, we will place the order of 11 set material to avoid missing for damage during manufacturing process. As you known, you will miss so component when setup the Pick and Place machine, especially small resistor and capacitor. In addition, the components itself have fail rate.
