UL PCB Assembly Service

High Quality PCB Assembly Services: A One-Stop Solution For Your Circuit Board

A full set of PCBA is our core business, even in the proofing stage. We use our professional and resources to do PCB proofing, material procurement, PCBA manufacturing one-stop PCB assembly services for you. If you want to solder specific devices, we will also provide such services.

Avoid the trouble of purchasing PCB components, make you focus on your PCBA design. Our purchasing team will purchase more components from the same supplier and use the best method to complete the purchasing task. We will optimize packaging (belt, tube, bulk, etc.) with quantity selection in smaller BOM to reduce cost. We have the ability to handle difficult-to-order materials and obsolete components. We purchase materials according to the material model and manufacturer in your BOM. Don't worry about the danger of any alternative materials. We will not change your design. Alternative materials will also be approved by you before use.

The price of the whole service includes welding cost, smooth plate cost, and material purchase cost. Quotations for electronic components are from Digi key, Mouser, Avnet, arrow, future, Newark, or designated suppliers. We don't charge any purchase fee.

We understand the importance of punctual delivery. In PCB fabrication, material procurement has been carried out at the same time. We will review engineering problems and component problems before welding. If there are no hard-to-order components and documentation errors, a full set of PCBA manufacturing usually takes two weeks.

How to get a one-stop inquiry of PCBA manufacturing?

BOM quotation, please send your BOM to iPCB, tell the number of PCB to be made, we will give you a PCBA quote within 24 hours. BOM must include quantity, tag number, manufacturer name, and manufacturer model.

Before the PCB assembly is delivered, we will carry out various tests on it.

- Visual inspection: general quality inspection

- X-ray test: check whether there is short-circuit cold welding or bubble problem in BGA, QFN, and another welding.

- Automatic optical detection: check whether there are false welding, short circuit, few parts, polarity reversal, etc.

- Online testing

- Function test (according to the test steps you provided)
